GPU crash dump

I keep getting GPU hang on my laptop. No specific steps to reproduce, just wait
for a bit. Screen starts to display some horizontal lines after that.

$ uname -a
Linux lantia 4.1.6-1-ARCH #1 SMP PREEMPT Mon Aug 17 09:07:24 CEST 2015 i686
GNU/Linux

$ dmesg:

[ 2064.006622] [drm] stuck on render ring
[ 2064.014748] [drm] GPU HANG: ecode 3:0:0x6affbfc1, in Xorg [507], reason:
Ring hung, action: reset
[ 2064.014759] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 2064.014765] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 2064.014770] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 2064.014775] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
