Kevin,

I was already describe possible culprits of Xorg screen puzzling after
resume, there is two possible candidates:
1. mishandling of system PM events by Xorg.
2. something wrong inside drm2+drm/kms drivers.

but things #1 in your list points more to mishandling of PM events.

btw, crash with suspendswitch=1 looks like fixed :)

Thanks!
