/sys/class/drm/card0/error output
I am occasionally experiencing GPU hangs on my computer. The configuration is a
PC with an Intel i5-5675C (non-overclocked) running Gentoo Linux with a 4.2.3
kernel.
The hangs seem to occur randomly, sometimes when running an OpenGL game,
sometimes when just sitting at the desktop idleing.
This causes the desktop to freeze for a few seconds. After the GPU has been
reset, it is back to normal.
dmesg output:

[147449.742726] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[147449.742727] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[147449.742728] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[147449.742728] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
