dmesg output after GPU hang

Sometimes on youtube HTML5 videos my screen freezes and then turns black. The
system is still active, I can e.g. reboot it blind by switching to console and
pressing ctrl-alt-del.

This is what dmesg shows:

[  293.705130] [drm] GPU HANG: ecode 0:0x9f47f9fd, in chrome [1294], reason:
Ring hung, action: reset
[  293.705132] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[  293.705134] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[  293.705135] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[  293.705137] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[  293.705139] [drm] GPU crash dump saved to /sys/class/drm/card0/error

I'll attach full dmesg and GPU crash dump.
