Random system lock-up or freeze / Linux 3.4

Hi
My system seem to regularly lock-up in the linux 3.4[1] series. Whenever this happens, I had to power cycle the system by holding down the power button. Keyboard, numlock, mouse wouldn't work. I'm still looking-out for a pattern that trips this lock-up consistently. The lock-up doesn't happen for days and can happen every other day as well.
During this lock-up nothing gets captured in the system log too. I parsed 'journalctl -a'. Here is a sample from such a lock-up:
Jun 30 18:01:01 chaembian /usr/sbin/crond[4747]: pam_unix(crond:session): session opened for user root by (uid=0)
Jun 30 18:01:01 chaembian /USR/SBIN/CROND[4748]: (root) CMD (run-parts /etc/cron.hourly)
Jun 30 20:45:03 chaembian kernel: Initializing cgroup subsys cpuset
Jun 30 20:45:03 chaembian kernel: Initializing cgroup subsys cpu
I noticed the lock-up around 18:30 and instead of forcing it to shutdown, I thought I would give it sometime to snap out of it. But nothing happened until 20:45, when I forced the restart. The only other anomalies are (picking out their first apperances):
Jun 25 13:57:33 chaembian kernel: BUG: Bad rss-counter state mm:ffff880115e10a80 idx:1 val:-2
Jun 25 13:57:34 chaembian kernel: BUG: Bad rss-counter state mm:ffff880115e10a80 idx:2 val:2
during shutdown
and
Jun 10 10:08:57 chaembian kernel: r8169 0000:05:00.0: eth0: link down
Jun 10 10:08:57 chaembian kernel: r8169 0000:05:00.0: eth0: link down
Jun 10 10:08:57 chaembian kernel: NOHZ: local_softirq_pending 08
during boot[2]
I'm not sure if these precipitate the lock-ups but these are the things that stand out in the logs for my untrained eyes.
> uname -a
Linux chaembian 3.4.4-2-ARCH #1 SMP PREEMPT Sun Jun 24 18:59:47 CEST 2012 x86_64 GNU/Linux
Let me know if you require any more information.
1 - I was a regular -ck patched user. Since the time the series started serving 3.4 series, I was having lock-ups. Since the stock was still at 3.3 then, I was using the stock as I was trying understand the issue from the logs. But ever since stock moved into 3.4, the lock-ups are happening in this as well. Again, since I have not been able to recreate the issue on demand, I'm not able to attribute the regression to 3.4 conclusively.
2 - A similar issue that was reported from last year will be System lock-ups or software resets, with increased ethernet activity. But the key difference is that my logs have just one instance of this message generated at the time of boot.

Yes, that's how I have it setup. Until today's forced power cycling earlier today, the journal had all the entries from June 10th. The system gets proper shutdown daily (there is a power shortage where I live and to counter there is a scheduled, daily power shedding for 1 hour).

[SOLVED]Random system freezes

Hello,
My Dell Studio 1558 runs ArchLinux with XFCE. Everything is fine except two problems: Random system freezes and slow wlan download speed. I think that those problems might be related.
Since some updates ago my Laptop will just randomly freeze. Unfortunately I cannot remember exactly when it started. The freezes will randomly appear without any regularity or possibility to reproduce. Sometimes it freezes immediately after booting, sometimes after some hours. Heating should be no problem as it also freezes when the Laptop is cold (what a joke )
Sometimes it will freeze several times in a row, sometimes it won't freeze a whole day. It seems that it only freezes if there is Wireless LAN connection available. (I use wicd if that is of any importance.). It feels like the highest freeze rate is while downloading packages for system updates...
lspci tells about the wireless chip:
04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)
uname -a
Linux mydell 2.6.38-ARCH #1 SMP PREEMPT Wed Mar 30 08:47:36 CEST 2011 x86_64 Intel(R) Core(TM) i3 CPU M 330 @ 2.13GHz GenuineIntel GNU/Linux
So, according to the wiki page I use the broadcom-wl driver from AUR. I also tried the DKMS one which, of course, changed nothing. My modules array concerning broadcom looks like
MODULES=(!b43 !ssb !lib80211 !brcm80211 lib80211_crypt_tkip wl)
I ran memtest over several hours to make sure it's no memory problem. No errors in 5 passes. It has an ATI Chip which is powered by catalyst right now... Could be the source of the problem but I guess I'd have to test that further.
Additionally I suffer slooooow download speed over wireless LAN since some periond (can't remember the exact starting point too...). It's not related to my AP, happens in other networks too. I tried several servers too. Max download speed: 148 kb/s :S
I suspect that the freezes and the slow download speed are releated. Maybe a driver issue? I have no clue. I was unlucky to find error reports in the logs after the freezes. Besides, I have no real idea what to search for in the logs. I placed a desklet on my desktop now, to see the exact time and seconds when the freeze appears. I hope I'll be lucky.
Can someone help me or give me some ideas what to do?
Edit:
There was another kernel upate and at least the low speed is gone... strange. Hope the same is for the freezes :S
Edit 2:
Downgrading pm-utils to 1.3.0 did the trick for me. No freezes anymore.

So, the freezes are still there. I also tried the open source ATI driver. My laptop will still freeze randomly. The highest freeze rate was during operations with pacman/clyde. I think this might point to either WLAN or HDD.
I placed a desklet clock on my desktop and I could finally see the exact time when my laptop froze! But I cannot find anything interesting in the logfiles.
This should be the last lines that were written before the freeze occurec in everything.log.

My laptop sometimes hangs at boot with this screen. I cannot take some usful information from it. But it seems, that it's also related to networking stuff? But I am not sure if that's the cause for my problem.
I am lost. I have no real idea what to do. I think of using some other distribution in order to see if the freezes will occur there too. I hope this is "just" a driver issue...

Verify Disk results, confusing.. Can they be the cause of system lock ups?

I have been experiencing strange freezes on my Mac Pro 2008 system.
My boot disk is a 50% full 128GB SSD from Crucial and is running beautifully fast however for the past couple of weeks my system often freezes for anything from 3 seconds to 30 seconds and then the Finder restarts.
After the Finder restarts everything continues running smoothly. As if nothing ever happend, no error reports, no apps crashed, nothing.
I have verified disk permissions and verified the disk itself in Disk Utility but I am not quite sure what these results mean and if they could be the cause of these random lock ups.
here are the results:
Verify permissions for “Boot Disk”
Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent" has been modified and will not be repaired.

Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk.
I would really appreciate it if someone that knows their way around this stuff could help me troubleshoot this.
As for the problem of the system locking up it does not happen in the same application consistently.
Often it happens in Firefox but it could equally often happen when working in Photoshop, browsing files in the Finder or trying to access the Spotlight search via the keyboard shortcut.
When the system locks up I get the spinning beach ball and I can still move the mouse and click and even still access CMD+TAB app switcher, switch spaces and all those things, just applications become non responsive.
If you need any more details please let me know.
Thanks for reading,
Jannis

These are innocuous errors that you may safely ignore. However the disk error is a problem. Do the following:
Repairing the Hard Drive
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

Odd System Lock-Ups [XP-Pro SP3]

Something odd is happening, on my normally, and otherwise stable laptop with XP-Pro SP3.
I have observed that on Fridays, at about 11:30AM MST/USA, I get system lock-ups. Everything just freezes.
I have poured over Event Viewer, and nothing is getting launched at about that time. Really nothing in System, or Applications, from about boot-up, other than my Browser (Chrome). Not one Warning, or Error, and little real activity.
I cannot verify that this happens every Friday (do not remember it on Friday Jan. 13, for instance, but then the Adobe Forum Log-in went down), as I am often out of town. However, and based only on memory, this has now happened about 5 - 6 times, and always late in the morning, and on Fridays.
Normally, I only have my Browser open, though this time also had Windows Explorer minimized. During this AM, I had PrPro, PrE and Photoshop open at times, but none was open, when the lock-up happened.
I tend to suspect something is trying to update, but it's not showing in Event Viewer. A few times, there was a Norton Live Update Scan, but those were usually hours before. Those are not download/installs, as I have Live Update to full manual, and the same for all other such utilities.
Does anyone have any ideas, or perhaps a monitoring utility, that will gather data, better than Event Viewer?
TIA,
Hunt

hmm.... google.... i dont really trust google much....
i used to have something ( i use xp ) that basically I had total control over when to connect to isp etc and disconnect... but for life of me cant remember what it was. that was years ago.
now when i start computer it automatically ( partially this is due to isp of verizon ) connects and then gives me control of computer ( is part of boot and load process now ).
your prob seems to be some kinda scheduled thing is why i was thinking maybe turn stuff ' off ' that might be trying to update or something under the radar ( is part of the system more or less.. components ...)
this area
you wont see this related stuff in event viewer type listings ... and gets kinda complicated to me at least.

What os a system lock pin

I was watching a movie on my MacBook Pro 13" Early 2011, when the whole display freezed, I tried to force quit but it didn't work and then i held the start button until my laptop switched off. I pushed the start button again and after the laptop switched on a "Enter Your System Lock PIN code to unlock this Mac" appeared. I haven't typed any PIN code when i was creating my user... What should I do?

Z68A-G45(B3) System locked up and screen artifact w/ IGP

CPU: Intel Core i5-2500K (stock)
Mobo: MSI Z68A-G45(B3) ATX
RAM: 2X2GB Mushkin Silverline DDR3 PC3-10666 @ 1.5V (stock)
Video: Intel HD Graphics 3000 (IGP) connected via DVI
HDD: WD WD4000AAKS 400GB SATA3
DVD: Sony Optiarc AD-7240S 24X
PSU: Corsair CMPSU-430CX 430W
Other: 1 120mm fan and 1 140mm fan
OS: Windows XP SP3 32bit
New system build, no OC attempt at all
Problem:
System can lock up at random time, even during startup or in BIOS screen. It accompanied by screen with artifact. (will show pic)
Testing done:
Clearing CMOS thru Clear CMOS button, as well as taking out the CMOS batteries out for a minute
Check voltage in BIOS and they looked fine
Changing BIOS setting from (Integrated Graphic Adapter) PEG to IGD
Reseating the CPU, even though the CPU never hit above 37 degree at BIOS screen
Tested individual RAM module in each slot
Ran Memory-Z and passed the test; Didn't tried Memtest86+ because I doubt the system will last the entire run
Tried replacing the PSU with an Antec Basiq 430W
Unplugging everything and leaving only the CPU, CPU fan, 1 module of RAM, and HDD
Observation:
When system locked up with the artifact on screen, the mouse is dimly lighted and flickered when it's clicked.
All 4 CPU Phase LEDs lit up, but the three on the right are dimmer than the one on the left and it appears that they are flickering.
Screen with artifact with vertical and horizontal line
CPU Phase LEDs where one is bright while the other 3 are dim
Is the mobo the problem? I doubt this system will use more than 300W peak without a discrete GPU and no OCing. Appreciate all the help I can get. Thanks.

Quote from: Henry on 06-October-11, 10:12:40
Re-seat the CPU and check the CPU socket for bent/damaged pins.
That Corsair PSU should be more than good enough for your rig.
I re-seated the CPU and checked the socket, no bent/damaged pins.
Quote from: NovJoe on 06-October-11, 11:18:30
If resitting the CPU and checking the CPU socket still returns same results, I suggest you test your processor in another board and see if the same artifacts came up.
Wish I have a spare board to rule one or the other out, but I don't have one. Is there any other test I can do? Can putting a discrete card in the system rule out anything?

System lock ups when using hard disks

At first I thought I had the same issue as in this thread however after reading his logs I decided that it is unlikely since the topic opener seems to be getting a bunch of
Apr 4 17:00:15 daxteriv slim[708]: (Do:882): GLib-CRITICAL **: Source ID 46 was not found when attempting to remove it
, so I decided to start a new thread.
I am not getting anything in my logs when I look at them after the crashes. It seems as if whatever is causing the issue makes it impossible to write to the drives so nothing seems out of place until after it's too late, and quite obvious that something is wrong. The sole exception to this was some complaint about ata9.00, however this seems to have been a red haring since the complete removal of this drive solved nothing, though it did make the error go away.
I have run memtest, and prime95 (in windows since at the time I didn't want to boot my system) both coming back negative. I also checked for SMART errors, particularly UDMA errors. Again, negative.
Here are some previous threads of mine that I believe to be all related to the same issue:
https://bbs.archlinux.org/viewtopic.php?id=195449
https://bbs.archlinux.org/viewtopic.php?id=193937
https://bbs.archlinux.org/viewtopic.php?id=192704
[edit3] My previous thought was that this was a btrfs issue, however now I think it may be more hardware related.[/edit3]
Last night I was writing urandom to a new drive and I woke up in the morning to see that it had stopped prematurely, but not due to lack of space. The system had not locked up completely, which was new, however, as soon as I did something that accessed the disks (tried using the Gnome Dash), all hell broke loose. I immediately hit the power button, which would start a shutdown. I didn't know about REISUB, or I would have tried that. In anycase the shutdown failed and I had to hard reboot.
The evening before I was playing games just fine and doing normal activities.
Also, the other day, while booted into the live cd I think it started to crash since it was acting extremely bizarre, but I shutdown, successfully, before it could do more than complain a lot. At the time I was in the middle of scrubbing a btrfs volume after a system lock up. I think, but am not certain, that I saw on my motherboard "A5" which, according to the manual indicates "SCSI reset", but I had an extremely bad viewing angle. I know neither if what I think I saw was correct, nor do I know if the system was again in the process of a meltdown.
In general there is no activity that seems to be able to instantly trigger this, though in each case, if my memory serves me well, there was a constant stream of data either to or from a HDD.
My set up is that I have 5 HDDs, and an SSD. One HDD has Windows, my fallback installation of Arch, and daily backups. Another drive, which I just installed a few days ago currently only has single 50GB btrfs partition that is not part of any sort of larger volume. I also have three other drives each with four parttitions each involved in a btrfs volume. At the top is a 175 GB volume in a RAID0 configuration, after that is a 25GB partiton in RAID1, then a 650GB partion (RAID1), and the remainder of the disk (about 80GB) is in single. The RAID0 is has games on it and sometimes for short term storage (a few hours), the 25GBx3 RAID1 is used for Arch as well my ~/.local, ~/.cache, ~/.thunderbird, ~/.mozilla, and ~/.config. The 50GB partition I mentioned is currently doing the job of this volume, and was not mounted last night, but has been before. The 650GBx3 is used for long term storage of just about everything, in particular ~ is mounted here. The single configured volume is used for downloads, storing ISOs and installers. The SSD is used for caching those partitions used in the RAID0 volume with bcache. I DO NOT think this is a bcache issue since the RAID0 volume has never had any errors.
My motherboard is a ASUS X79-DELUXE which has the SATA controllers: Intel X79 Express Chipset, Marvell 9230, ASMedia 1061.
[edit] Oh, I'm on kernel 3.19.2 and btrfs is 3.19.
[edit2] Also, I converted the RAID0 to a single in case that matters.
[edit4] I finished scrubbing and copied my "journalctl -b" output to pastebin. I can't see any thing that might raise any flags. http://pastebin.com/WXpbpTuc

nstgc : it's hard to tell if your problems are memory related, but memtst often needs multiple passes to detect errors.
How many passes did you let it make ?
Is it possible for you to take out say half of the memory chips and see if that changes anything ?

System Lock-ups. What can be wrong?

On to more serious issues.. .
I am experiencing system lock-ups on the brand spanking new computer I just buildt.(Yeah, yeah.. . Anti-static and all other thinkable precautions were taken.. .)
Needless to say it's annoying the hell out of me. I can't work and I can't play with a situation like this.. .
The system just hangs and the only solution is to press the reset button.
This usually happens in games or when scrolling a window. Less frequently it also happens when doing nothing. It only seems like it's getting worse - more frequent that is.
Are there any known issues with TwinMos RAM and nForce2?
The RAM and CPU are running on the same clock. The error persists when running the RAM at it's native clock too.
I'm running Catalyst 4.11 and Bios Information says 113-95702-100.
The BIOS of the MB has not been flashed by me - as out-of-the-box.
Nvidia drivers version 5.10.
No overclocking of any sort of any device.
I will be running the full monty in Memtest x86 over night, but the RAM DIMM is spanking new and has been handeled with the utmost caution. The first five tests returned nothing wrong.
Another peculiar hick-up is that sometimes after the lock-up and after I've pressed the reset button the BIOS seems to take forever to detect the IDE devices. If I power off and on again, the IDE detection happens in a snap. Very, very strange.. .
Edit: I have a sneaking suspicion that it gets worse until I power off/on - after that it will take a longer time for the error to return. I haven't verified this empirically, but I have a hunch.. .
I really hope there's someone with helpful insight to this problem out there!
Thank you for your time.

Woops. Seems like I don't have access rights to the last link.
It seems like downflashing to B30 is the only way to go for me as I'm having *major* stability issues, even with no overclocking.
Heck - I even had to reset and reboot the machine when trying to write this post just now!
I must say I've never experienced such outrageous instability with any of my other MSI MBs before.. . Not from any other make for that matter. This is just incredible.
I'll flash it tomorrow (if I can find a damned floppy somewhere). For now I really have to work.
Fingers crossed!
Thanks again for great input!

System Lock Error while reset & reversing the cleared document - FBRA

Hi Experts,
Currently using t-code FBRA, when user trying to reset & reverse the cleared document , they are facing "System Lock Error". We have analyzed on this issue and found SAP note no. u201C487347 u2013FBRA: Overflow of the lock table in production systemu201D . After implementation of this note, SAP has created one new transaction code, FBRA_LOAC.
However, when we tried to reset & reverse the cleared document using t-code FBRA_LOAC, we face the same error.
Can you help me to resolve this issue ?
Thanks in advance.
Regards,

Hi:
We once faced these issue and got it resolved by extending parameter after extending the profile-parameter "enque/table_size", as per note note 13907. Do not forget the restart the server after extension.

That sounds like it's requestion the Find My Mac passcode. If you don't know it, you'll have to take it to a nearby Apple store with proof of purchase/ownership as only they can unlock it for you.

System locks up when trying to play streaming media after installing i-tune

Hi Folks,
Ive just bought the greatest piece of kit ever, a 2Gb Nano.
Great kit but since installing i-tunes my system locks up whenever I try to play any streaming media (wmv etc) via windows media player. Cntrl-Alt-Del even locked out. Total lock up.
Ive tried re-establishing file types in quick time and windowd media player and even installed lasted windows media player but all without success.
I'm using WinXP pro SP2.
Any ideas?
Cheers,
Gene Stevo.
