Hi This affects me also. 

I can reproduce the issue 100% of the time by opening up the Chrome Webstore
(https://chrome.google.com/webstore)

I could not get a screen dump as my machine became unresponsive after the hang.
I copied down the main line pertaining to the problem after I entered tty
(please note -this may not be complete - I did not get the line numbers)

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

The file: /sys/class/drm/card0/error was empty when I rebooted and looked for
it.
