After a resume the GPU hangs and the 3D acceleration is very slow.


[ 1710.007256] [drm] stuck on render ring
[ 1710.008312] [drm] GPU HANG: ecode 0:0x772a3d58, in Xorg [1560], reason: Ring
hung, action: reset
[ 1710.008316] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 1710.008317] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 1710.008320] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 1710.008322] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[ 1710.008323] [drm] GPU crash dump saved to   


This is happening on a Mint Linux with cinnamon. I'm not sure if this is still
in the current version a problem but it accrues in 2:2.99.910-0ubuntu1.6 of
xserver-xorg-video-intel.
