gpu crash dump

When zooming in Google Maps using Chromium Web Browser, chromium and gpu hangs
with the following dmesg output:

[drm] GPU HANG: ecode 0:0x85fffffc, in chromium [397], 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
[drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp off

I am able to reproduce it every once in a while. Attached is the last gpu crash
dump I've got.
