[fglrx] soft lockup, CPU0 stuck for 11s!

This happens on my IBM T60 laptop whenever I blank the screen (e.g. close the latop lid) and, sometimes, when I suspend to RAM. I'm running Ubuntu v8.04 with the fglrx v8.4 binary driver. I can provide any other details needed.

--alphabeta

I also get the same behavior if I leave my laptop idle. I come back to it and it's frozen and I need to hard reset.

I've attached my syslog. It seems to repeat the lines in my syslog over and over (approximately 100 times per second) until it freezes. dmesg does not give any relevant information.

Switching back to the 2.6.22-14-generic kernel does not give me any issues.

Please attach your /var/log/Xorg.0.log.
It would also be useful to have a full backtrace on this issue - please see http://wiki.ubuntu.com/X/Backtracing.

Probably don't need the xorg component.

I am also experiencing this when trying to do a standby. I am running Kubuntu 8.04 and ATI 8.5 drivers.

I have exactly the same problem on my Lenovo T60 / Ubuntu 8.04, linux kernel 2.6.24-16-generic and fglrx 2.1.7412. The system freezes about twice a day when left idle for some time.
Lots of soft lockup errors are written to the syslog ("BUG: soft lockup - CPU#0 stuck for 11s! [Xorg:5856]").

I started to get the same problems on my Toshiba laptop with Ati Radeon X1400, soft lockups, e.g.:
Jun 21 08:21:50 pyty2 kernel: [ 1942.999751] BUG: soft lockup - CPU#0 stuck for 11s! [Xorg:5517]
I can provide more info if necessary..

Perhaps the difference from other reporters is that it does not need to be idle.. it also happens when I work on the laptop..

Well I have updated to the latest 8.6 drivers. The problem appears to go away. Does anyone else see this after updating?

This has not happened to me since an upgrade to the newer kernel(s) in 8.04

Zenigata, please indicate if you're still seeing this problem, and if so attach your /var/log/Xorg.0.log and a backtrace.

I confirm this issue and I attach text/plain with a similar stack trace.

I do not play with hibernate/suspend/standby options. I have a workstation Opteron 1222 running 24 hours. It usually happens when running Multimedia player (Kaffeine, VLC, and mplayer), often with H264.

Nonetheless I saw a similar Bug:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/240071

and last message says kernel 2.6.27 solves it!
It is related to a networking issue -not a fglrx-
(I can confirm I always had a networking client with heavy input/output when crash occurs).

I consider this issue critical because it locks the computer completely, and renders the kernel useless (all threads and processes hangs).

As of Intrepid (8.10), we have a dedicated package 'fglrx-installer' for fglrx bugs, which now includes a process for upstreaming bugs to AMD.

  http://bugs.launchpad.net/ubuntu/+source/fglrx-installer

To transition your bug into the new fglrx-package, we need your help. Please do the following:

 a. Verify the bug occurs in Intrepid.
     (Intrepid ISOs: http://cdimage.ubuntu.com)
 b. If you haven't already, please include in the bug:
     * Your /var/log/Xorg.0.log
     * The output of `lspci -vvnn`
     * Steps to reproduce the issue
 c. Click 'Also affects distribution'
 d. Set 'Source Package Name' to 'fglrx-installer'
 e. Click Continue

Thank you. This will assist us in reviewing and upstreaming your fglrx bug, as appropriate.

[We'll expire the fglrx bugs in l-r-m-* in a month or so.]

Well I did not encounter that bug in intrepid, I don't know if it's fglrx or the kernel, but intrepid seems much more stable than hardy on my cpu, no more black screens etc..

Marking fixed then. Glad it worked out for you.

hello, is this fixed in the hardy LTS (long term support)?
my hardy crashes at least once every week.
attached syslog, if you need more information, tell me.

I am suffering from this problem from time to time since some weeks, too.

My notebook is a Lenovo R60.

This is the syslog from today's crash.

I have hardy and installed updates today. The crash occurred after applying these updates.

uname -a says:

Linux musca 2.6.24-28-generic #1 SMP Fri Jun 18 12:02:15 UTC 2010 i686 GNU/Linux

Hardy has seen the end of its life and is no longer receiving any updates. Marking the Hardy task for this ticket as "Won't Fix".
