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.=C2=A0 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.
