[Kernel 2.6.32] Random lockup / panic

Sadface · 2010-01-05 13:45:06

Heya, recently my system has developed the habit of seemingly
random crashes. I have failed to find the cause for this behavior,
but I think it's rooted in the kernel.

The problem is as follows: Booting and working and everything is
fine, until this kicks in. Basically it looks like the Kernel is crashing,
the mouse won't move, the keyboard won't work (I think pressing
the numlock didn't turn on the status LED aswell, if I remember
correctly), and the screen freezes (my taskbar clock doesn't change
anymore). I have to hard-reset the machine, because nothing else
will work anymore. I don't know WHAT broke it, I only remember
the last 2 potentially problematic updates were the nvidia driver
and the Kernel.

The nature of this crash is very much like the AMD freeze bug
that can happen when some program tries to access bare hardware,
such as sensors (AMD OverDrive on Windows XP often freezed the
whole system), however, this has never happened before, or it
has always been there but has never happened before.

I checked the kernel.log, Xorg.log, messages.log, everything.log,
dmesg.log but nothing helped me, it's like the kernel just froze to
death and had no time to write anything into the logs.

After the last crash today I set up an SSH server to find out if
just Xorg crashed on me, or if the whole system failed. At least I
hope this will be any indicator.

I REALLY appreciate any help with this!

What kind of information do you need to help me find that nasty
problem's root?

Thanks in advance

I have exactly the same problem, I also could not find anything in any of the log files but downgrading to Kernel 2.6.31, nvidia 190.42.1 and nvidia-utils 190.42.1 fixed this problem for me.

I had two hard lockups within the last week on my 32 bit system. A common denominator I noticed was that I had chromium running each time this happened (ping ping, Are you using Chromium or perhaps chrome?). I then started using konqueror instead along with Firefox and have not had the problem recurr since (roughly four days). I suspect something related to flash and chromium but am not sure. I suppose I might test it a little though I am reluctant to invoke hard crashes since this is a production system used for my work.

Note: In my case I am fairly sure this started before the recent kerenel upgrade along with the nvidia driver (96xx).

I've been having lockups with a recently installed x86_64 + kdemod
A couple of days of lockups give me the impression that i can't load my system to the max.
file IO, net IO or video processing, I can max one out as long as the others aren't doing anything.

translates to => throttle downloads, don't do file copy's and let firefox take it's time to render before yanking the scrollwheel, this seems to postpone lockups to every couple of hours

the system just freezes, no output, no log files

axel · 2010-01-12 19:55:09

The same happened to me once while trying to start a VirtualBox machine. At that time I had x86_64, kdemod, kernel 2.6.32.3-1 and nvidia 190.53-2. Now I've updated to nvidia 190.53-3 and didn't have a freeze since then. I don't know if it was nvidia the problem or something else.

I have had similar issues after an upgrade. Searching on Arch forum and other locations did not provide any specific solutions. In my case, X crashed and possibly kernel panic when connected on external DVI display. This happened every time I locked my screen manually or after a timeout the screensaver kicked in. For logs, /var/log/Xorg.0.log will not help as they would be the current ones. For previous logs (since you mentioned about a hard reset) you might want to look into /var/log/Xorg.0.log.old file. If there is a seg fault with stacktrace that probably shows you the issue.

In my case, Downgrading the kernel did not work, so did disabling KMS in kernel parameters. This seems to be related to some bug with Xorg and hence downgrading xorg-server to 1.6.3 seems to have worked fine. With this, you might also have to downgrade few other packages like xf86-input-evdev, and xf86-video-* drivers. This version of xorg works fine for me even with the latest kernel 2.6.32-3.

Not in my case as I dont have Chromium or Chrome installed

Not in my case either, Im rolling KDE free.

Also i have nothing in any of my old logs to indicate what has happened, this has really got me stumped.

I also forgot to mention that double buffering doesnt work on my system after the downgrade but it worked fine before, conky just sits there flickering at me now. Not sure if its at all related!!??

yannickkiekens · 2010-01-13 12:28:13

I've read my /var/log/Xorg.0.log.old

There's nothing indicating a crash or error, there are some warnings about an RV730 chip beeing found but on an unrecognized card and that the card has more memory than expected so it will use only 256 MB (should be 512 ) except the memory thing, everything indicates all will be fine

When doing nothing (boot with kdm to std kdemod desktop) X works as expected

When doing large file copies, X becomes completly unusable, switching to a terminal and then back to X ruins the modesetting (weird colors and wrong resolution) but X doesn't lock up or crash.
You can wait for the file copy to finish and then restart X
Fiddling with nice values during the copy crashes the system. (tried to up the priority of firefox a bump)

Running a gui torrent program without throtling will lockup the sytem before i maxed out my internet line

Running a throtled gui torrent program works as long as i don't use my scrollwheel in a browser scrolling with the scrollbar works always, using the wheel has a high chance of locking up the system

I am now trying an unthrottled console torrent program, hasn't crashed yet

I am beginning to suspect X
I'd rather have an upgrade then a downgrade

Any idea's to gather info?

kank · 2010-01-13 12:46:29

I'm having similar issues, both on my acer aspire one and on my desktop (both intel graphics) since the kernel update. No reaction to keyboard input or mouse movements. Sometimes I can switch back to a console but not restart X without a reboot. I also don't feel like downgrading because my wifi is finally working flawlessly.

I actually found something in dmesg - it might not be exactly the same problem as the others are having:

[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
render error detected, EIR: 0x00000000
i915: Waking up sleeping processes

[drm:i915_wait_request] *ERROR* i915_wait_request returns -5 (awaiting 15514 at 15513)

There's a bug report that describes exactly this:
http://bugs.archlinux.org/task/17705

Sadface · 2010-01-22 12:47:38

Oh, I already had given up on this, because of the lack of answers, but at least I'm not alone.

It happened 3 times in the last 24 hours now. Pressing any of the keyboard LED keys won't light them up
Not capslock, not numlock or scrolllock, so it's a kernel problem.
Not just the display, also every connection to it gets killed (MPD, SSH for example) and won't be able to reconnect.

Like many of you, I'm running x86_64 (AMD Phenom II X4 640) with nvidia (GeForce 9800 GTX+) and KDEmod, so maybe it's that.
RAM doesn't fail, I ran Memtest86+.

I can't find ANY reason, it crashes just randomly, whether I'm on tty0 or in KDE...
All I can do is wait for 2.6.33 and hope it fixes that for me...

Any news on your sides?

Nothing new here, the only thing that worked for me was the downgrade. For me the issue is definately not KDEmod as I have a no desktop environment installed.

If anyone has any ideas I would also be interested in hearing them

kalpik · 2010-01-22 17:43:26

I am experiencing the same thing Its totally random! And started happening only recently..

Sadface · 2010-01-24 16:21:57

It's neither the RAM nor the nvidia driver, I'm running nouveau right now, but it's still freezing.. running out of ideas here..

ctrler · 2010-01-25 09:21:45

Hello.
Untill yesterday I was using the testing repo and having this lockups. Today I downgraded to stable but I'm still having the lockups.
I have an Intel GM965 graphics card and there is nothin on the logs. The lockups seem random and completely freeze the laptop, I have to hard reset.

mgangav · 2010-01-30 01:17:53

Yeah, I have the exact same problem. I have an intel 950 graphics card, Acer Aspire lappy. My logs don't seem to indicate anything bad.

If it helps anyone, I have some experience with this problem (I am forced to reboot my system like 3 times a day atleast...)

If you start the X server using startx from the console, try seeing if you can go to getty1 by pressing Ctl+Alt+F1 and then Ctl+C'ing the x server.

If you cannot do this try to see if the kernel itself has crashed. Check this by toggling the Caps Lock or Nums Lock keys and seeing if the corresponding keyboard lights also toggle. If your keyboard lights do respond, then your should use the Magic SysReq key sequence to try and reboot your system without harddisk errors:

Alt+SysReq/PrintSrc+{R,E,I,S,U,B} in that order with about a 5 second gap between each press. Note that the Magic SysReq sequence does not work by default. To enable it, you need to go to /etc/sysctl.conf and change the kernel.sysrq flag to 1

Well, that is all I know for now, is there anyway to stop my system from randomly crashing?

jithin1987 · 2010-01-31 13:06:31

I am facing freeze in 3 occasions.
1. when system is idle for some time.
2. during suspend to ram.
3. during shutdown/reboot.

All the cases are pure random except the 1st one. This is highly annoying.
I use intel GM965 and I have kms enabled.

Hello,

Well, I upgraded to the latest kernel version, and I haven't had X crash on me randomly yet (3 days since). Now, I only need to get my wireless card working right....

nichlas.johansson · 2010-02-02 22:04:35

Hi Sadface.
Im seeing almost the same symptoms on my rig and i think i narrowed down the culprit to ACPI problems.

when using acpi=off in /boot/grub/menu.lst problems seems gone for me.
Maybe its enough to disable powermanagement from bios (haven't tried that yet ).

Something fishy is going on at kernel.org it seems.

Snakeye · 2010-02-03 01:04:24

Same symptom here. Is everyone here running kde? I noticed my clock app was always corrupted, not loading. So i removed the clock app and calaender app and the freezing has stopped, no crashes so far in a day. Just wondering if it is a KDE thing not happy with the latest kernel patches.

Sadface · 2010-02-03 15:11:22

I have no idea what caused it. I wiped the system and reinstalled, and it has since been fixed.
I think it was something the Chakra authors put in, a module that has been broken with recent updates
maybe, at least that was my case

Since I reset my system, nothing has happened, ever.

No, awesome here. Seems like the WM doesn't matter.

Snakeye · 2010-02-04 21:29:42

Yeah your right, had another freeze yesterday. Seems to be a fluke when it happens but nothing gets logged.

Damnshock · 2010-02-04 21:43:54

Did all of you guys use flash by any chance? I've been without freezes for the whole day since I stoped using flash.

Hope that helps in some way...

kalpik · 2010-02-06 06:35:56

Hmm.. I see when the system hangs (freeze, keyboard/mouse does not respond), i can still login to the system via SSH and restart the machine. Is it a different issue?

mgangav · 2010-02-22 14:10:11

I don't think that flash is an issue here.
