GPU hung ERROR => nothing is displayed on screen anymore.

[Pieter L.]

Binary package hint: xserver-xorg-video-intel

Since my upgrade to Ubuntu 11.04 with Unity, I sometimes have a GPU hung error in which case it seems the screen is 'dead' and does not show anything anymore.

Here the error:

May 26 13:02:42 ubuntu-server kernel: [22293.856048] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
May 26 13:02:42 ubuntu-server kernel: [22293.856069] [drm:kick_ring] *ERROR* Kicking stuck wait on render ring

The system remains trying for every while to get control over the GPU, but without any effect. The lines above are repeated every couple of seconds in the logfile.

If I do a Remote shell to my ubuntu machine it seems that the machine works without problems except for the videocard.
If I do a reboot, everything works fine immediately again (including the videocard).
In Windows7 (my system is dualboot) I have never experienced any problem with my videocard.

I have a Intel® Desktop Board D945GSEJT motherboard with an ATOM 1.6 GHz processor on it and with an onboard i915 GPU chip.

In an earlier version of Ubuntu I have had a problem with the videocard as well, after an upgrade to that version a strange problem occurred which caused my Xwindows to freeze completely.
This was eventually fixed with upgrading to a higher version of the Linux kernel, but it seems related to not be able to get control over the GPU (that is at least what I remember).

Info of my motherboard:
http://www.intel.com/products/desktop/motherboards/D945GSEJT/D945GSEJT-overview.htm
It has the latest available version of the BIOS inside.

I have no clue how to continue and to get this issue solved.
If I would have known on forehand I would not have upgraded to 11.04, because I want a stable system.

Does anyone have any suggestions?

Might be related to: #690201 and to #732304 but I don't think it is exactly the same.

Can anyone respond to this? Is more information required? Please let me know.

I get exactly the same issue as described above. Screen just goes blank (although is responsive i.e. music still plays and can stop with keyboard) and after a forced reboot logs show:

I've now had this several times.

Status changed to 'Confirmed' because the bug affects multiple users.

Pieter L., 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>

Also, could you 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-rc1

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.
