/sys/class/drm/card0/error
After some upgrades (only graphics-related part was
xserver-xorg-video-intel:i386 from 2:2.99.917-2 to
2:2.99.917+git20151019-1~exp1) I sterted to recieve random gpu hangs. Sometimes
display become garbage and system hangs entirely (no reactio to alt-sysrq),
some times garbage appears but all continues to work. Suspend/resume was never
used.
Attached dump is from the "hangs but continues to work situation".
It crashed at night, nothing were done with computer. Window manager is awesome
with server-side composition by "xcompmgr -a". Also hardware-accelerated
chromium was running.
I'm using debian testing/expiremental with amd64 kernel and entirely 32-bit x86
userspace.

[39710.792060] [drm] stuck on render ring
[39710.796710] [drm] GPU HANG: ecode 3:0:0x00bbf88a, in Xorg [1117], reason:
Ring hung, action: reset
[39710.796719] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[39710.796722] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[39710.796726] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[39710.796729] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
