Crash dump retrieved from /sys/class...

Chrome crashed - this is a one off and not regular (so far).  No changes since
install of laptop around 10 days ago.

Whilst using Flash (Farmville 2) in Chrome on Arch Linux.  Using the browser
flag that enables hardware GPU, bypassing the built in black list which
includes Intel cards on Linux.

dmesg:
[226917.940518] [drm] stuck on render ring
[226917.940529] [drm] stuck on blitter ring
[226917.940533] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[226917.940536] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[226917.940538] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[226917.940541] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[226917.940543] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
