Graphic corruption with i915 (2.6.39.1)

Graphic corruption with i915 (2.6.39.1)

[Leandro Lucarella]

Hi, I've been experiencing sporadic graphic corruption since a few
stable kernel versions and I always thought "maybe is fixed in the next
release", so I upgrade, but I usually experience a different problem
then. This problems are exposed very rarely, maybe I have no problems
like for a month or so.

Now I'm using kernel 2.6.39.1 and I experience one of this problem so
I though it was time to report it. This is what I got in dmesg:

[368693.756008] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung

If you look in /sys/kernel/debug/dri/0/i915_error_state we can see what
garbage the DDX [xf86-video-intel] fed the gpu.

cannot access /sys/kernel/debug/dri/0/i915_error_state: No such file or directory

The debug directory is not present, should I boot or compile with some
particular option to enable it?

You need to compile with CONFIG_DEBUGFS and at runtime
"mount -tdebugfs debug /sys/kernel/debug".

The /sys/kernel/debug/dri/0/i915_error_state will only be populated
after a hang is detected.

OK, I had CONFIG_DEBUGFS but never mounted it. Unfortunately I rebooted
since the problem, so now that file says: no error state collected

I'll get the contents when it happens again.

I'm having exactly the same problem. It happens pretty randomly, but
I've noticed that the frequency in which it occurs is highly increased
when libflashplayer.so is used. Unfortunately I didn't compile my
kernel with CONFIG_DEBUGFS. I'll change this and if I come across
anything interesting, I'll let you know.

OK, I'm having another i915 "episode" and now I have the debugfs
mounted. Here is the contents of
/sys/kernel/debug/dri/0/i915_error_state:
http://llucax.com.ar/tmp/i915_error_state.txt (1.4MiB)

Here is the error message shown in dmesg:
