i915 drm GPU hung errors with kernel 2.6.38.2 on 82865G chipset

[wzab]

Today I have experienced two "GPU hungs" on machine with 82865G chipset 
working with 2.6.38.2 kernel
In the /var/log/syslog I have found the following errors:

Apr 15 22:50:51 wzab kernel: [drm:i915_hangcheck_elapsed] *ERROR*

Hi Wojtek,

Your best chance to see the bugs fixed is to report a bug following
guidelines at http://intellinuxgraphics.org/how_to_report_bug.html

For GPU hangs, collecting the error state (while GPU is hung) under
debugfs is very helpful.
Report contents of (as well as details on your software stack and
if know what kind of action triggered the hung):
  /sys/kernel/debug/dri/0/i915_error_state

Also you should CC intel-gfx@lists.freedesktop.org and Chris Wilson
<chris@chris-wilson.co.uk> for all issues regarding intel GPUs as
thats the place it has better chance of being seen by someone who
can help out. (intel-gfx is subscribers-only but at least part of the
thread would reach it)

Regards,
Bruno

As Bruno said there is a /sys/kernel/debug/dri/0/i915_error_state file
that contains a GPU dump at the time of the error which often contains the
vital clue at to what went wrong. If you can also think back to what was
happening on the machine at the time of the hang, that can also help
identify the trigger and the suspect code.

Thanks,
-Chris

Ooops, it seems, that my previous message with uncompressed logs was a 
little too big.
I'm resending it with compressed logs, even though they will be probably 
discarded in the archive as "unhandled content"

Hi,

After I've switched on debugging (booted with drm.debug=0x06 and mounted 
"sudo mount -t debugfs debugfs /sys/kernel/debug" the probability of the 
error decreased.
However after 2 hours or work it happened again.
There was nothing specific performed on the machine.
OK. This time I had the iceweasel window in the background, and was 
running an application under wine emulator, but previously
the same problem occured when I had only two gnome-terminals opened and 
iceweasel.
The problem may be associated with switching of active window in X or 
with switching of active tab in iceweasel (i.e. with activity related to 
massive change of displayed contents).
I attach the output of the i915_error_state.txt, the log of X server.
Sorry for big uncompressed files, but when I compressed them previously, 
I saw that they were ignored by archive website as "unhandled content".

I was not able to send the glxinfo, as after login via ssh to the hung 
machine and running "DISPLAY=:0 glxinfo" the command hung and didn't 
display anything.

I have also attached the output of "intel_gpu_dump" command.

Hi, just for info, I seemingly had the same error occurring yesterday, but I 
also failed to retrieve information from the debugfs. Also on 2.6.38.2, 
chipset being H55 Express. Seems to happen after a long uptime. I will be more 
careful to retrieve debug information next time.

Another sort-of-regression I noticed since moving to 2.6.38 is the 30 second 
waiting period when resuming. However, I have no idea what driver might be the 
cause.
