Kernel crash (General Protection Fault) under load or randomly

[Gregor Kališnik]

Hi.

By using the computer, the computer freezes. SSH doesn't work. Sometimes I get a trace printed on the monitor (will upload some pictures).

When I "apply" pressure which involves a lot of HDD activity, the crash happens earlier.

I have AMD Phenom 2 CPU. Using Radeon HD 4850 with latest open source drivers.

Crashes began on 20. 11. 2011 and I regularely update the system.

I've tested memtest for one pass, and it hadn't reported any errors.

Pictures aren't the best quality.

Distribution info:

Another interesting image

Gregor Kališnik, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc7

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

Hi.

I now have a completely different system.

Afaik, when I've upgraded to 12.04 the problem went away. So I would suggest closing it as fixed or invalid?, since I cannot reproduce the problem anymore.
