[14047.920290] [drm] stuck on render ring
[14047.921017] [drm] GPU HANG: ecode 6:0:0x84fefffc, in chromium [5029],
reason: Ring hung, action: reset
[14047.921018] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[14047.921019] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[14047.921020] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[14047.921021] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

I've been seeing graphics rendering issues for several weeks now (not so much
in Chromium, but very frequently in xfce4-terminal); probably due to driver
upgrades. Currently using "2:2.99.917+git20151217-1~exp1" from Debian
experimental. I will try downgrading to unstable to see if the issue persists.
I've titled this as "probably userspace" because of the experimental userspace
driver version.</pre>
