[ 85.435367] [drm] stuck on render ring
[ 85.436107] [drm] GPU HANG: ecode 0:0x85dffffd, in X [593], reason: Ring
hung, action: reset
[ 85.436111] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 85.436113] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 85.436114] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 85.436116] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

My distribution is ArchLinux with stock kernel 3.15.1-1. I do not see any
graphical corruption, the visual display freezes for a few seconds.
The last pre-compiled kernel that does not express this hang is 3.12.9-2.</pre>
