Could also try suspend without any GUI stuff in the way.

Cc´d Intel Gfx mailing list, in case somebody there knows something: Cc´d Thorsten for regression tracking… forgot initially.

It also may be something like CPU online/offline, however. I see. I wondered about intel-gfx driver already. Of course it could also be something else. I forgot to mention: The mouse pointer was visible, but the screen remained black. That may again point away from Intel gfx driver. There has been a MESA update in between in userspace.

There were almost no general changes related to system-wide PM between 4.18 and current, so I would suspect one of the device drivers or the x86 core.

There were almost no general changes related to system-wide PM between 4.18 and current, so I would suspect one of the device drivers or the x86 core. It also may be something like CPU online/offline, however. Thanks, Rafael

People are taking a With 4.19-rc2 this ThinkPad T520 with i5 Sandybrdige sometimes hangs with black screen when resuming from suspend or hibernation. With 4.18.1 it did not. Of course there have been userspace related updates that could be related.
