[SOLVED] BCM4312 with b43 module, unusable

Hi all,
I've got an old Lenovo S10 netbook that I'd like to use while my main is being repaired after spilling coffee on it. Everything's working except the wifi. Unfortunately it's a Broadcom. The wiki alludes to problems with kernel 3.8+, but does not give any specifics. The wifi worked the last time I put arch on it, maybe 1-2 years ago. Any help is appreciated.
I've got b43 enabled and installed b43-firmware from AUR. I have also tried the broadcom-wl proprietary drivers (with zarel's suggestions at the bottom of the wiki article), doesn't work either.

There's a function key for it, here's what that does, before and after:

Actually, I just noticed that there is another button next to the power key... At first I thought it wasn't doing anything, but after holding it (and putting the other back to 'before'):
0: ideapad_wlan: Wireless LAN

And then I tried to "ip link set wlan0 up" it again, and in dmesg I see:

But NOW when I do "iw dev wlan0 scan" I actually get output!?!?! I'm not really sure what's going on, but it seems to be working... Going to try enabling my netctl profiles and rebooting.

[SOLVED] errors with fdisk and cryptsetup; is my drive going bad?

I'm having issues with re-formatting an external hard drive using dm-crypt. It was previously formatted with TrueCrypt/NTFS, which I used as a shared backup drive between Windows and Arch. At some point, it stopped being able to mount, which I attributed to allowing Windows to "fix" it after improper dismount (e.g. a hard kill).
I decided to re-format with ext4 and only use it from Arch, but now I'm wondering if I may have a hardware issue with the drive. I've tried a lot more (like going through the full zero write after mounting the drive as a temporary dm-crypt device), but here's the condensed version to illustrate the problem.
system info
This is on a fresh boot. Just adding that as I've had issues with kernel modules after updating if a new kernel comes through. A fresh boot removes that potential issue.

Things also tend to hang with respect to the drive at this point. For example, fdisk -l spits out /dev/sda partitions immediately and then just hangs instead of printing out /dev/sdb info, then eventually quits (without ever writing it).
Any suggestions on where to look/how to troubleshoot? I found some possibly related posts, but nothing that looks promising:
- Impossible to crypt the drive using cryptsetup (fixed by rebooting)
- cryptsetup fails to open Udev cookie 0xd4d94f5 (semid 0) waiting for z (no responses; the hang after seems similar)
There's a couple odds and ends references to cryptsetup 1.6.6 having issues. I downloaded 1.6.4-1 and 1.6.5-1 and -2 from ARM to try, but wanted to post this in the meantime in case something stuck out.

@qinohe I thought of that and the other day started formatting with mkfs.ext4; unfortunately, it was at work and I had to leave before I could let it finish. It had been chugging along a good few hours, and I was surprised it would take that long. I was able to format it with ext4 using Windows 7 (I dual boot) with the MiniTool Partition Wizard but I didn't use it like that before trying to solve the cryptsetup issue again.
This last time around, I was getting unresponsive behavior. I think I need to reboot each time I try something with cryptsetup, as any commands related to that drive seem to hang afterwards (fdisk, umount, eject, mkfs, or trying crypsetup again). Perhaps I'll just let it cook overnight with mkfs and see if I can at least have an unencrypted, but functional drive.
One interesting tidbit is that even though cryptsetup fails, when I've tried to issue mkfs afterward, it asks me to confirm that I want to format the disk since it has a LUKS header... so something appears to have been written. Is it possible the header is causing some issues? I don't know much about the structure of a disk (like what range the MBR resides in, what constitutes a header, etc.) but have been wondering if there's some way to start really, really clean with the disk. Like I'd just bought it -- something appears to be lingering around from previous efforts?
@frostschutz I'll check tomorrow. That's a good question. Just checked journalctl and here are some of the errors that appear; unfortunately, I wasn't watching so I can't tell you what matches up with what command:
May 23 09:32:22 arch_840 systemd-udevd[7784]: inotify_add_watch(7, /dev/sdb1, 10) failed: No such file or directory

May 23 09:32:19 arch_840 kernel: blk_update_request: I/O error, dev sdb, sector 490735616
### there's also a bunch like this, from tab #0 -> #29 (not colored red, so not sure they're errors?)
May 23 09:32:19 arch_840 kernel: sd 2:0:0:0: [sdb] tag#0 CDB: opcode=0x2a 2a 00 1d 07 bc 10 00 04 00 00
May 23 09:32:18 arch_840 kernel: sd 2:0:0:0: [sdb] tag#0 uas_eh_abort_handler 0 uas-tag 1 inflight: CMD OUT
I paged down quite a ways and those seem like the unique messages when I search the journal for "sdb". Anything stand out? I will say that the same sector numbers appeared in multiple blocks of the third error type listed, so that makes me wonder if something is genuinely wrong with the disk. I'll post the output of the full smartctl scan when I hopefully run it tomorrow.
Thanks for chiming in!

Wireless does not hold connection with b43 driver!

Hi everybody!!
It's my first time here in the forum, so nice to meet you.
I have a laptop Acer Aspire 3050 and I recently formatted it to install the new Arch 2009.08.
It's pretty cool, but I can't make my wireless card (Broadcom BCM4318) work with b43 driver. It worked very well with Arch 2009.02, but now it's a pain!
It recognizes the driver, loads it and connect with no problems, but when I ping my desktop machine, it says that unfortunate message "Destination Host Unreachable"
It sometimes works when I do these commands about 5 or 10 times:
./connect
ping 192.168.0.1 >>> Destination Host Unreachable
ifconfig wlan0 down
rmmod b43
/etc/rc.d/network restart
modprobe b43
./connect
[... many more times]
but even when it does connect, it usually can't hold the connection for more than 15 or 20 minutes. And I have to do it all again.
Hear goes some info on configuration files so it may help you:

I've already tried many different configurations in rc.conf, but it still does not estabilish a connection in the first try.
I'm using the driver from the wiki (http://mirror2.openwrt.org/sources/broa … .5.tar.bz2) and did not try with only ndiswrapper. It's because I want to have all functionalities from criptography and... after all, it was supposed to work, wasn't it?
Where could be the problem? The driver version? Or bad configuration?
Thanks in advance!! If you need more information, please ask.

So, the same problem occurred and in a relatively shorter time than before. I began to think that something is causing this problem.
My theory is that it is a VMWare software issue. What I've been doing differently recently is using it in "Unity" mode as opposed to "Full Screen" mode. My guess is that the program is modifying my wireless permissions and screwing it all up.
So, what I've done is set the "Network Adapter" to "Host-Only". This denies the VMWare program internet access but still allows file sharing between the Windows virtual environment and the Mac hard drive.
Then I had to re-install Mac OS X all over again to fix the wireless settings/permissions mess.

To get selected rows from alv output which is prepared with funciton module

Hi ,
I have a program which is prepared ALV with funciton modules.
Now i have to get selected rows(more than one).
Can i use method CL_GUI_ALV_GRID -> get_selected_rows.
or any other way to get selected rows.
thanks,
shyla

Under the callback subroutine ( u have passed them in I_CALLBACK_USER_COMMAND of ur function module) - u do like this -
DATA : ref1 TYPE REF TO cl_gui_alv_grid,
t_selcted_rows type LVC_T_ROID.
CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
IMPORTING e_grid = ref1.
call method ref1->get_selected_rows
importing ET_ROW_NO = t_selected_rows.
Hope this solves ur problem.

for allocation structure you have to co-ordinate with your FI/CO team,

> Maintain Allocation Structures ---> Creat New Entries for allocation structure define PM-Allocation structure for PM than select and goto assignment .... then define assignment for example, external procurement, internal material, labor etc etc and select one of them goto source define cost element for that from here you have to co-ordinate with your FI/Co team and your problem will be solved ( define source than settlement cost elements etc)
Activity types we use for work center (Internal labor costing), In activity types we can assign the rates and so on with the help of FI/CO, HR and than assign the activity type in the work centers ......

[SOLVED] Problem with "su" and "login".

Hi, I reinstalled Arch Linux today when I updated "filesystem" and reboot appeared an error with root device, but I solved with installation CD.
I restarted laptop after solving error with root device when I went to XFCE4 and open a terminal I tried to login as root with "su" and "su -" but showed this error:
bash: su: command not found
So I rebooted to start in text mode.
When loaded SLIM I press ctrl+alt+F1 to enter text mode.
I type root to login but did'nt appear to enter the pass, appeared again to enter login. I tried type my user but did the same.
Someone can help me?
Thanks!

Thank you falconindy. I upgrade with --force because I search in Google the problem show "filesystem" when I tried install and I read that solution is upgrade "filesystem" with --foce.
I tried to reinstall util-linux and now works. Thank you!

How do I use Cisco MARS to monitor two ASA (active/stby) with IPS modules?

Hi
The two ASA with IPS modules are in active/standby mode. When I try to add both the two IP (active/standby) into the MARS, the MARS will complain duplicated hostnames.
How to setup MARS to monitor ASA with IPS with active standby topology?
Thanks!

Hi,
The fundamental problem with this scenario is that you have non-failover capable modules in a failover chassis - think of the ASA failover pair as one device and the IPS modules as two completely separate devices.
Then, as already mentioned, add only the primary ASA. (The secondary will never be passing traffic in standby mode so it's not actually needed in MARS) Then, with the first IPS module you can add it as a module of the ASA or as a standalone device (MARS doesn't care). With the second IPS module the only option is to add it as a separate device anyway.
In a failover scenario the ASA's swap IP's but the IPS's don't so whereas you'll only ever get messages from the active ASA you'll get messages from both IPS IP's depending on which one happens to be in the active ASA at the time.
Don't forget that you have to manually replicate all IPS configuration every time you make a change.

Using a different user(other than default PI user) with adapter module

Hi,
We are having a custom adapter module built to interact with a Hardware Security Module(HSM). This custom adapter module by default uses a PI user configured in the system. However, we are not able to pass commands to HSM because of insufficient authorizations to this PI user. Now, we do not exactly know the permissions required for the user to access HSM. We have asked the HSM support team about the same. However, I wanted to explore the possibility of using a different PI user to work with the adapter module and eventually pass commands to HSM.
We have an admin user configured which has all the necessary authorizations. Is it possible to use this admin user created on PI system to work with adapter module so that it passes commands to HSM?
Thanks,
Ravi Desai

We have given the necessary authorizations to PI user.

Need help with the Modulation Toolkit to configure a QPSK Modulation

Hi! I'm
trying to build a CDMA system with the Modulation Toolkit to use it later with
a PXI-RF Product as a part of my thesis (I don't remember the exact model
number because it's in my university and I'm home right now, sorry). But my problem right now is, I assume, a very simple one.
I'm having
some trouble understanding the MT Modulate PSK.vi and the MT
Demodulate PSK.vi since I have them both connected and the output bit stream is
not the same as the input bit stream. I'm guessing it's a problem with the sync
parameters in the MT Generate Synchronization Parameter.vi because maybe I
don't really understand how the sync bits work. I tried using a simple
sync header but the output bit stream is always shorter than the input and shows
only a little portion of the input bit stream and some of the 1's I used to
create the sync header, and it gets worse when I increase the number of input
bits.
I'm
attaching the simple vi I created to try to understand the mod-demod vi's, so
if someone knows what I'm doing wrong it would be great if you let me know
since I'm stuck in my thesis and understanding this issue will let me continue
with the project.
Thanks a
lot in advance!
Daniel

Latvian Language support for generated PDF's with FPDF module for PHP

Hello !
I have a problem with Adobe Reader for Android. I am working with online PDF creation with PHP module named FPDF.
With FPDF module for PHP you can create PDF's online.
The problem is that - when generated PDF appears on phone it doesn't show Latvian language ( cp1257 or ISO-8859-13 for example ). For example - "ŗķļņž" and "ŖĶĻŅŽ" is shown with other symbols.
However opening the same file with standart app "Polaris Office" - the text is show as it used to be, without problem.
Strange bug, that i can't fix from PHP ( Tried a lot of decodes and encodes ). Also i have saved PHP file with different encodings - nothing helped.

You might ask about this in the regular forum. There are several form experts there that may be able to help you.

Problem with develop module

I have LR 5.4 running on a mac OS 10.7.5. I am having problems with the software locking up in the Develop module. Sometimes a new image won't open and the preview screen stays black. I go back to the Library module and try to reneter the Develop module and get an error message saying there was an error trying to open the module. The entire LR screen is gray. I have to quit LR and restart the software to continue. I downloaded my software from Abobe and I was wondering if I can download a new version again and use my same serial number to reinstall the software.

Hi Rodney,
No custom print templates and this is a relatively new problem. It just
started about a week ago. I have been using the software steady for months
now. It did it once or twice last week but this weekend and today it has done
it about six times so it seems the problem is getting worse. That¹s why I
think the software may have been corrupted. I didn¹t keep a copy of the
software I downloaded so I can¹t reinstall. That¹s why I was wondering if I
could download it again and use the same serial number as before. I have only
loaded the latest version on my desktop. I also have LR 4 still installed on
my laptop and desktop. I have a big project to complete and this is really
slowing me down.

Do you have any custom print templates? That might be the case, it was an
issue at one time. Delete them and try using one of the default presets.
Crash?
