Hi,

After resume from hibernation (suspend to disk), initially all system is not
responsive (can move mouse but keyboard does not work nor does the caps lock
light change on pressing), after a while (like 20-30s) can type again and login
via display manager.

User gets gets logged in, but after a few seconds it becomes unresponsive
again; goes black and after a while I get the desktop back but if I try to move
the mouse or interact with anything it flickers.

Checked the logs and got following output from dmesg:

[   84.718912] [drm] GPU HANG: ecode 8:0:0xa7e661f7, in Xorg [2580], reason:
Hang on render ring, action: reset
[   84.718915] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[   84.718917] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[   84.718918] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[   84.718920] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
