Content of /sys/class/drm/card0/error after hang

Hi,

a switch to the tty1 and a restart of the whole system. According to the pasted
entries in the kernel.log below i should report a bug in here.

kernel.log entries:

[drm] stuck on render ring
[drm] GPU crash dump saved to /sys/class/drm/card0/error
[drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including
userspace.
[drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI ->
DRM/Intel
[drm] drm/i915 developers can then reassign to the right component if it's not
a kernel issue.
[drm] The gpu crash dump is required to analyze gpu hangs, so please always
attach it.
