3 seconds after resume from suspend, chromium's "/usr/lib/chromium/chromium
--type=gpu-process" process was using 100% cpu and had to be killed:



kernel: [drm] stuck on render ring
kernel: [drm] GPU HANG: ecode 8:0:0xfffffffe, in chromium [26167], reason: Ring
hung, action: reset
kernel: [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack,
including userspace.
kernel: [drm] Please file a _new_ bug report on bugs.freedesktop.org against
DRI -> DRM/Intel
kernel: [drm] drm/i915 developers can then reassign to the right component if
it's not a kernel issue.
kernel: [drm] The gpu crash dump is required to analyze gpu hangs, so please
always attach it.
