<pre>Kernel: 4.9.4-1-default, openSuse Tumbleweed
After resume from s2disk, PC hangs, screen flickers and desktop is
unresponsive.
dmesg includes these lines after wakeup:
[22470.597775] [drm] GPU HANG: ecode 8:0:0xba399353, in Xorg [1652], reason:
Hang on render ring, action: reset
[22470.597778] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[22470.597780] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[22470.597781] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[22470.597782] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
