intel graphic card hanging (Hangcheck timer elapsed... GPU hung)

[Norbert Preining]

Dear all,

(please Cc)

I am running 2.6.34-rc2 + git 01e7770 commit (yesterday) with KMS on Debian/sid:
xserver-xorg: 7.5+5
video-intel: 2.9.1-3

Running D2X-xl (self compiled) (descent2 open source code) X suddenly died,
and after that gdm could not be restarted because after a few secs
it went dead again.

In the logs I see:
kernel: [ 2486.341227] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
kernel: [ 2486.341240] render error detected, EIR: 0x00000000

Stopping gdm and restarting didn't help to get the graphics card back to normal.

If you have any ideas how to fix/track/debug that please let me know,
same if you need more information.

I was seeing something similar on my 945, can you try this patchset?
It seems to make things much more stable for me.

http://lists.freedesktop.org/archives/intel-gfx/2010-March/006387.html

There are 7 patches starting with that one.

Tried it with git kernel commit b72c409 and your patches, but
didn't change anything. Starting d2x-xl killed the X server:

Anything else I could try?

One of my 945 machines became pretty stable after increasing the
hancheck timeout from 75 to 750 jiffies in i915_drv.h.  But I have
reports that it doesn't work on all machines, so it's probably just
covering up a bug somewhere else.

GLknots works fine (I tried a couple of times and I never got the GPU
hung message in dmesg). BTW, X crashes when I have the error (or
sometimes it gets rendering corruption, but continue working besides
that).

We've seen a similar hang with PineView when GLknots screensaver mode
is running.  Run /usr/lib/xscreensaver/glknots, and the screen gets
frozen immediately (mouse works, so the rendering simply doesn't
work), and no way to recover until reboot.

Hi. I just wanted to say that I was hitting this bug too. It seems to be
a problem associated with xscreensaver and/or OpenGL. Looking for
information on the web I found some bug report that said something about
OpenGL (I can't find it now) so I tried deactivating xscreensaver and
the system is working very stable, no GPU hungs in 10 days of uptime.
When I had xscreensaver active the X server crashed in a couple of days
and sometime I got the GPU hung error in dmesg but X didn't crashed.

Thanks.

And then I thought, that's what I'm gonna use it on.
Why am I judging this poor bastard.

Hi. I just wanted to say that I was hitting this bug too. It seems to be
a problem associated with xscreensaver and/or OpenGL. Looking for
information on the web I found some bug report that said something about
OpenGL (I can't find it now) so I tried deactivating xscreensaver and
the system is working very stable, no GPU hungs in 10 days of uptime.
When I had xscreensaver active the X server crashed in a couple of days
and sometime I got the GPU hung error in dmesg but X didn't crashed.
