Workaround data point: On Acer C720P, using linux-oem kernel (4.15.0-1065-oem) suspend works fine. Using 5.3.0-nn causes instant boot on wake after suspend. I've not tried 5.0.0.
I'm pinning 4.15 for now but would love to run current. When it fails the log stops after "PM: suspend entry (deep)". Now that it works, here's what's in the logs at that point: Jan 9 15:08:54 systemd-sleep[3361]: Suspending system... Jan 9 15:08:54 kernel: [ 434.199460] PM: suspend entry (deep) Jan 9 15:08:54 kernel: [ 434.199464] PM: Syncing filesystems ...
