<pre>Similar error for me, Ubuntu 14.04:
[12592.559357] [drm] stuck on render ring
[12592.559362] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[12592.559364] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[12592.559365] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[12592.559366] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[12592.559367] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
I have attached the crash dump (previous comment).
I do not know if it is related, but I see from time to time lines on the screen
that look like problems with cache flushes.</pre>
