I have seen a bit of a screen distortion at the bottom of LCD on Radeon
after a wakeup.
I tried to re-run with drm.debug=0x0e, however once I did it - the
problem has disappeared, and I have not been able to duplicate it again.
So just watching for now.
OTOH I have seen (only one time) a black screen after wakeup on Nvidia.
So maybe some timing is now exposed in PM / DRM...
