Fix hibernation with S0 target state
> Created attachment 137788 [details]

There's the following:
[ 64.041878] Unexpected DBuf power power state (0x0000000a)
during resuming. One possibility is that hibernation happens with an S0 ACPI
target state (or at least target state < S3) and because of that we won't
reinit power domains during resume. That's a failed attempt on my part to fix
this issue in an earlier patch. Could you try the attached fix on top of 4.15.6
to try it again (and attach a log)?
In the log there is also the
[ 69.146901] [drm:skl_check_plane_surface [i915]] requested Y/RGB source size
7680x4320 too big (limit 8192x4096)
error, that one looks like user space asking for an invalid config and
unrelated to the above.
