Good morning/afternoon. Applied this patch to the latest mainline, but
still see the black screen upon trying to resume after suspend. The
keyboard looks to be unresponsive, as trying to switch to a tty
terminal or back doesn't result in anything happening(as well as
numlock/caps not being responsive either). I also tried using the power
button, as well as closing/reopening the laptop lid to see if I could
trigger resume. 

Checked the systemd journal just in case, but no splats or anything
else is recorded after the suspend. Finally, attempted following dmesg
with -Wh to a text file before suspending, but that also doesn't record
any new input after the suspend.
