Navigating to http://www.google.be/ in Chromium with hardware acceleration
enabled and typing in my home address causes the following message to appear in
the kernel log:

[drm] stuck on render ring
[drm] GPU HANG: ecode 0:0x85fffff8, in chromium [10619], 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.
