GPU crash dump from /sys/class/drm/card0/error
While running Borderlands 2 on an Asus UX303LA running Ubuntu 15.04 (Wily) it
hangs very often. Usually it hangs in 1 or 3 minutes after a game starts, on a
good day I can play for about 15~30 minutes before the first hang.
Happens on 15.04 mesa drivers as well as the ones from oibaf
(<a href="http://ppa.launchpad.net/oibaf/graphics-drivers/ubuntu">http://ppa.launchpad.net/oibaf/graphics-drivers/ubuntu</a>).

[ 561.366852] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 561.366853] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 561.366854] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 561.366855] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

I'm not sure if this is related, but every time I start my computer I see the
following message in dmesg:
