[Solved]SSD x25-m not in DMA mode, kernel issue?

Is DMA mode enabled in the kernel? (For HDD)

It is, I checked with hdparam -i /dev/sda and it told me that udma6 is enabled.

Some programs crash but not in safe mode or for guest user

Hoping that some talented and kind Mac wizard will help me solve a bizarre problem: Some but not all of my programs have started crashing immediately upon launch, but not in safe mode, nor when I log in as a guest user.
The problem began on February 5th, right after I installed an update to my OS (bringing it up to version 10.7.3), which included an update to the firmware for my computer, a Mac mini from mid-2010. The programs that began crashing upon launch *may* be those that were open at that time, but I can’t be sure. They include Adobe Reader, Picasa, Word for Mac, and a sweet little utility called uCalendarX.
Specifically what happens with, say, uCalendarX, is this: After I launch it, nothing appears on screen for a few seconds, and then comes a message that it is trying restore its windows, with a choice of whether to attempt restoring them or not. After a few more seconds comes the news that it has quit unexpectedly. The first several dozen lines of the crash log appear at the end of this posting.
So far my troubleshooting has revealed the following:
(a) When I reboot in safe mode, the programs that crash now work normally.
(b) When I boot the usual way but log on a guest user, the programs that crash now work normally.
(c) Fully emptying the trash made no difference.
(d) The problem was not solved by restoring my hard drive (via Time Machine) to its state the day before I downloaded that update to the OS and the firmware. (This was a drastic step, the intervention of last resort, and I was sure it would work. But no. Perhaps I did not go back far enough for the restoration.)
(e) Deleting the plist files and plist.lockfiles made no difference.
(f) Deleting the files for the app under Saved Application States made no difference.
(g) Disabing the user’s font cache (as happens in safe mode) made no difference.
(h) Uninstalling Adobe Reader, emptying the trash, downloading the latest version, and installing that made no difference – this latest version newly installed continues to crash (but not for a guest user, nor for me, the administrator, in safe mode).
(i ) Repairing permissions on the hard drive made no difference.
I will be mighty grateful for a solution to this perplexing, vexing problem!
B.t.w., I don’t know Unix but was able to do all those (fruitless) interventions listed above.

Thanks for thinking about my problem. I've already experimented with creating a new user, a co-administrator. The programs don't crash when that account is running, just as they don't crash when the guest-user's account runs. So it seems that the problem is limited to the default user's account, which is the one that was running when I installed the updates to the OS and the firmware. Another clue is that the programs that crash as soon as they are launched are *probably* the ones that were open at that time in that account. Yet deleting Saved Application States does not keep the programs from crashing when next launched.
So the mystery continues, but these additional facts will help with the diagnosis, I hope.
Thanks again for your suggestion.

OSX Mountain Lion 10.8.4: imessage works fine in safe mode, but not in "normal" mode. Any hints?

My iMessages does not work in "normal" startup, but it works perfectly in safe mode.
Any hints?
I have the same problem on a MacBook Pro 17" and on a MacAir 13" mid 2011.
On my MacMini, iMessage work's fine.
I'm using same apple ID on all 3 devices.
Before update to 10.8.4, i had no problems.
FaceTime also stopped working after update to 10.8.4.
Thanks in Advance,
Lars O.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below on this page to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -f -a TextEdit
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; sudo defaults read com.apple.loginwindow LoginHook; sudo crontab -l; } 2> /dev/null | open -f -a TextEdit
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
{ launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; crontab -l 2> /dev/null; } | open -f -a TextEdit
Step 4
ls -A /e*/{la,mach}* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -f -a TextEdit
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of every login item' | open -f -a TextEdit
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

Fixed Value Date at line item level is not in changable mode when copied

Dear SDN Team,
Hi i have a problem in the Fixed Value date at the line item level in the Return sales order.
The Problem is When creating the return order with reference to the scheduling agreement (10.03.2010). In the Return sales Order at the line item level the fixed value date is coping from scheduling agreement item (fixed value date eg: 31.12.2009)
But i would like to have the fixed value date in the return order as 10.03.2010 but the field is greyed out.
But normally when the sales document is created with reference to the preceding document the same will be copied. But field is greyed out and it is not in changable mode.
Can any one help how to solve this.
I have checked also SAP Note where i did not find any messages.
In normal scenario - when the order is created without any reference the fixed value date is in changable mode until the document is in open.
Pleas help me to resolve this.
With Regards,
Jai

Hi Lakshmipathi,
I am sharing the resolution which was done to this requirement.
We have a specific condition type with statisticaly used and with routine to have KWERT with zero value,
Based on the different key combination. We have a specific key combination for the SA and SDoc and for this we need to maintain a condition record for the condition type with fixed value date and which will be linked to only the specific document. Once this is done.
We need to do update pricing in the sales order for the particular line item. by doing this the Fixed value date will be changed in the particular line item.
Thanks and Regards,
Jana

Master-detail page with form layout -- insert only -- not in create mode

JDeveloper 10.1.3.1 with JHeadstart
I have the following master-detail structure in JHeadstart:
Group 1, Table a, Layout: table-form
Group 2, Table b, Layout: table-form
Group 3, Table c, Layout: form
Group 4, Table d, Layout: form (on same page as master table c)
Table a, b and c are updatable (insert, update and delete).
I have problems with the last page, tables c and d, master-datail both in form layout.
The master-table (c) is not an insert-only table, the detail table needs to be an insert-only form on the same page as the master table c.
Settings Table d:
Advanced search and quick search: none
Autoquery: disabled
Single row insert allowed (other options in Operations disabled)
In my view object I have used the settings in the JDeveloper guide 8.1.2 ('no rows...' in tab Tuning).
I run my application in JDeveloper (with the option run in my ViewController-project, which means that I am not running my detail page directly in JDeveloper??) and when I open this last page, the detail form is not in create mode (I see no rows found and a create rows button).
I have read several threads in this forum, but I do not know how to solve this problem.

This does not work.
In my first post I made an mistake in describing my application, it is not a table-form, but a tree-form application:
Group 1, Table a, Layout: tree-form
Group 2, Table b, Layout: tree-form
Group 3, Table c, Layout: tree-form
Group 4, Table d, Layout: form (on same page as master table c)
If I override the executeQueryForCollection method in the ViewObjectImpl of table d I get a message ('JBO-27122: SQL-fout tijdens voorbereiding van statement' and 'java.sql.SQLException: OALL8 is in an inconsistent state').
while clicking on the tree (with table b and c). It seems that the QueryForCollection method is being executed to early.

Error 10846 occurs only if DMA mode for transfer ist selected

Hello,
my problem is if I use the DMA mode to for transferring data to the PCs memory always the error 10846 occurs.
I perform the buffered semiperiod measurement with a continuous buffer (circular buffer).
I tried to use Interrupts. The error does not occured.
Is this a known problem?
I read another thread in this forum. But there are no useful answers up to now.
I'm thankful for any hints.
Regards Peter

Hi Peter,
The NI-DAQ Help Manual gives this description for the error:
"Your application was unable to retrieve data from the background acquisition buffer fast enough so the unretrieved data was overwritten with new data. To prevent this error, you might increase the size of the background acquisition buffer, increase the amount of data you read from it per call to the read function/VI, slow down your acquisition rate, or reduce the number of tasks your computer is performing."
This is all valid info because I believe that your acquisition rate is on the verge of being too fast for your buffer size and the number of data points you are reading into your application each time. Therefore, DMA, which is a faster transfer mechanism to get data from your c
ard to the PC memory is probably loading the PC memory with many samples until it catches up with the data acquisition card where as Interrupts will gradually transfer the data to the PC memory. This means DMA is bursting data to a PC memory buffer that is slightly too small while Interrupts are transferring at the same rate you are reading (unless you change your acquisition rate depending on the transfer protocol).
I think the only change you need is to increase the size of your buffer (PC memory). If that doesn't work, also increase the number of points you read from the buffer each time by your application program. There will be a balance between these two numbers that will allow smooth operation with DMA. Hope that helps.

Can I have a general daq event in visual basic while outputing in dma mode?

Hardware: PCI-6711
Software: Visual Basic 6.0
NI-DAQ 6.9.3f3
Windows 2000
I can't get the GeneralDAQEvent_Fire subroutine to happen. I'm trying to output two synchronized waveforms on two channels at sampling rates that can be changed on the fly. To do this, I've set the clock source of the channels to be the GPCTR1. I output on a pulse train on the GPCTR1 and adjust the pulse widths to vary the frequency. I need to be able to switch to the new pulse width at a precise time so that the correct samples are output at the correct samplerate. I want to generate a general daq event which fires whenever a certain number of pulses (and thus samples) on the GPCTR1 have been output. I will
then reset the event and output samplerate within the GeneralDAQEvent_Fire subroutine for the next section of samples. I need to output at up to 1 MSample/second, so I need to be using DMA mode. I have not read anywhere that DAQEvent 0 Aqcuired or Generated n Scans requires interrupt mode, am I wrong about this? I have set my Channel string to CTR1, does this reference the GPCTR1? I set the board, DAQTrigVal0 and enabled properties and then call the refresh method. Is there something else I should do?
I have been reading the NIDAQ Function Reference Help and the NIDAQ for PC Reference manual and have not found a solution. Any suggestions? Also, where can I find info on what the ConfigureDaqEvent method is supposed to do?

Roz,
First of all, I think you will want to use DAQ Event 1 since you desire for a message to be sent after every N updates. This will be more efficient than removing the current message and adding a new message each time the event fires. Furthermore, DAQ Events 0-2 can all be used with DMA transfers. However, you will be unable to use a counter channel with DAQ Events 0-2. Instead you should use one of the analog output channel you are clocking with the counter's output.
Good luck with your application.

GX600 cant change from PIO to DMA mode

Hi
I have a very irritating problem with my GX600.
I have currently switched my OS from Vista to XP.
My secondary IDE Channel is currently stuck in PIO Mode.(Which causes DVD's, Audio CD's and Burning to Lag terribly.)
I have tried uninstalling the IDE channel but there's no success on reboot.
Could someone please help with this problem.
Thanks

Quote from: mjohnny on 20-November-08, 16:55:00
had a similar problem back then. WinXP Sp2. For some reason my 2nd hdd was set to PIO mode. I uninstalled it from the device manager, then restarted my system. After you log on to windows, it will reinstall some host driver again. Then it will be set to DMA mode.
Pardon for not being clear with the terms i used. I'm on a different OS now and I'm not using the old box anymore.
I have tired this and it did not work...
Does anyone have XP on the GX600?
I will try and update the BIOS and im hoping it will work.

SSD Crucial MX100 not defined in HP Pavilion m6-1040er

Hello!
My HP Pavilion m6-1040er not defined in the BIOS SSD Crucial MX100. Notebook BIOS updated to the latest version F.36. SSD firmware update not available. SSD working on a home desktop PC (determined immediately after installation) and HP ProBook 6560 (determined after updating the BIOS to the latest version). Please help.
PS. Excuse for my bad english.

Hi @alex_yuri ,
Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue about your HP Pavilion m6-1040er Entertainment Notebook and needing help with the new SSD. Here is a link to restore the BIOS.
Restoring the BIOS should pick up the new SSD.
Did you check before purchasing the new SSD to see if it was compatible? It shows me different specs.

Ultra DMA mode 6

OK, after numerous tries, I failed to boot from IDE3 with the moded bios 5.6 that let you use ide3 and ide4 as normal ide channels. Now don't even ask me question about that, I don't want to here anything related to this.
Now I have flashed again to the standard bios version 5.6. I have my DVD-RW master on IDE2 (Ultra DMA mode2 = 33.33MBps = optimal) and my CD-RW as slave (multi word DMA mode 2 = 16.6 MBps= optimal ). My hd is master on IDE1. In my bios it says my hd is running in PIO mode 4, in windows xp it says it's running in Ultra DMA mode 5 (which I assume is UDMA100= not optimal). Why can't a ATA133 certified motherboard and a ATA133 certified HD can't work at UDMA mode 6?
I'm getting nervous here, I want my hd in UDMA mode 6!!!!!!
Yes I use 80 wire cable. And my hd is alone on it's channel, nothing could stop it!
Is it XP? MSI? me?!?

Yes - the standard IDE ports are ATA-133/UDMA-6 compliant. I don't know how to make WIN-XP show them as UDMA-6 but I'm sure someone else will. It isn't really important however as current ATA-133 drives do not perform better than a good ATA-100 drive.

Problem: KT3 Ultra2 and DMA mode

hi there,
everytime i wanna make an image of a CD with nero or some other CDR progs, it takes years to finish it. i got only a tranfer rate of 800kb/s - 1.400 kb/s (btw: there is no copy protection...this happens even on normal data cds)
i got my HDD and CDRom on IDE1 and my CDR and DVDRom on IDE2
in winXP it tells me:
IDE1:
0: UltraDMA Mode 5 (Hdd)
1: PIO
IDE2:
0: UDAM Mode 2 (DVDRom)
1: MultiwordDMA Mode 2 (burner)
CD Rom Teac CD-540E Firmware 3.0A (IDE1 Slave)
Burner Benq CD-R/RW 24x10x40 Firmware P.QJ (IDE2 Slave)
DVD Rom Pioneer 104 Firmware 2.06 (IDE2 Master)
i tried to reinstall the latest via drivers but nothing worked.
sometimes winXp tells me
that IDE1 device 0 is running in udma 2 mode...but than on the next reboot it's again on pio mode.
i checked the ide cables and changed the CDrom with the CDr and it show me UDMA2 now...but it didn't speed up the transfer rate...it still runs only with ~1.400kb/s :(
maybe the ide cables are corrupt???
apart from that i tried the latest bios drivers for my Mainboard but they didn't seem to solve that prob.
are there any options to check and enable the DMA mode on both IDE channels?
hope someone can help me
TIA

AMD XP 1800+

Hi,
Try switching your CDRW Drive to Master setting. Sometimes it doesnt like slave.

DVD running as Multiword DMA mode 2!

I noticed since upgrading to my new system that both my CDR and DVD drives have been very slow. I'm talking 1 minute to copy a 50MB file for example! They are both running on the same P-ATA channel, the CDR is master, DVD is slave. In the device manager it reports the CDR is running in "UDMA Mode 2", but the DVD is running in "Multi-word DMA Mode 2". I beleive this must be the reason its all so slow. This was not a clean XP install, I just carried my drive over from my old intel system.
Any ideas how I can get the DVD running in UDMA Mode 2?
Thanks

Can you think of another reason my optical drives have both gone horribly slow since I upgraded? :( I assume that installing the Intel inf files for this mobo would ensure that the correct drivers got used for the drives.

Setting IDE device to DMA mode?

Recently my DVD has been burning superslow. It takes 24 min to burn a full disc at 8x. It should be 8 min only! Then I saw that my Drive is in "PIO" mode in the hardware settings. I'm using WinXP Pro so in the device manager I tried looking in the IDE ATA/ATAPI controllers to change the DVDRW to DMA but it's already has "DMA if available" chosen.
I tried looking in the BIOS and DMA is set to "AUTO".
Anything else I can try? My MOBO is a MSI PM8M-V, VIA chipset...
DVD drive is a BenQ 8x (older one forgot model).
The only thing I can thing of is I updated the BIOS with MSI live but that was quite a while ago...
Anything else I may have missed that is not DMA related that is causing the slow burn? I'm just buring ISO images with Nero.

Uninstall the IDE Channel in Device Manager on which the drive is installed (e.g. usually Secondary). Restart and enter BIOS, set UDMA for that channel/drive to Disable. Save and Exit BIOS.
Boot into Windows normally, allow the controller channel and drive to be reinstalled, then restart again. Enter BIOS, set UDMA back to Auto or Enable, Save and Exit BIOS.
Hopefully this will clear/reset the registry flag that is forcing the driver to disable DMA.
Also, leaving UDMA disabled in BIOS will still permit the drive to use DMA mode (Multi-Word DMA 2) as long as 'DMA if available' is selected in Device Manager, which is not as fast as UDMA, but hugely preferrable over PIO.

Ultra dma mode 5 does it matter?

Hi
If I connect one of my maxtor diamond 9 sata hardisks to the promise sata controller, the boot up information says the promise controller is using ultra dma mode 5. My question is what is the correct mode that a sata drive should use? Should it be ultra dma mode 6, or is the dma mode at all relevant for a sata drive?

its fine it matters not at all when drives on the controller

K7N2 Delta2 - Multi-Word DMA Mode 2

Well, I was having problems getting windows XP to access my Seagate SATA 120 Gig Hard Drive at anything other than Multi-Word DMA Mode 2. Finally figured out what I had to do. After messing with cables and SATA connections and generally mucking around for several days, I decided, just for giggles, to enable RAID.
Did not want to run RAID configuration but it worked. The listing in windows Device Manager now shows the drive as Ultra DMA Mode 6. When you enable RAID in BIOS make sure to go in and enable it for SATA as well (consult manual). When I rebooted it asked to hit F10 to set up RAID, this I ignored. Finished booting into windows and new hardware wizard started up. Inserted floppy disk (included in Motherboard bundle) with the NVIDIA raid drivers. That was all. I expect that if you are experiencing similar problems with ATA disks, it might work there too. Hmmm, maybe I will give that a try next!
I had sent a number of email to tech support and they never mentioned this, food for thought!

Another update just came in from MSI support;

Would you please follow the steps below to verify?
1. connect to the SATA HDD to SATA1 on the MB;
2. boot system up and enter BIOS, Load Optimized defaults; set Integrated PeripheralsàOnboard DeviceàSerial ATAàEnabled;Save&exit setup;
3. enter OS, go to Device Manager, expand IDE ATA/ATAPI Controllers, right click NVIDIA nForce2
SATA Controller and select Properties,choose Primary Channel,then check what transfer mode the SATA HDD works at. We suggest you capture the picture and send it to us. Thanks!
Well, since I was already connected to SATA1 I decided, why not. Maybe third time is a charm (installing the NVIDA drivers that is). So I downloaded the drivers from their link, installed, and rebooted. I now have NVidia MCPS2S Parallel ATA Controller (v2.6) and NVidia MCPS2S Serial ATA Compatible Controller (v2.6) in the device manager under "IDE ATA/ATAPI controllers".
When I checked the details of the Serial ATA controller the Seagate drive shows up as Serial ATA DMA for transfer mode. When I checked the Parallel controller my IDE drive shows up as Ultra DMA 5 - Ultra 100 for transfer mode. Looks like all is good now and as it should be.
NOTE: had to disable RAID on a reboot to get drive to show up in Windows...hmmm. It worked what can I say!
Thanks to the people at MSI support for convincing me to install the NVidia driver set again.
P.S. NVIDIA nForce2 System Drivers for MCP2S
God I like it when a plan comes together! Hooah!
