[Bug 1848771] Re: Reboot after resume from suspend (deep)

[Ralph]

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 ...
Jan  9 15:08:54  kernel: [  434.217766] ehci-pci 0000:00:1d.0: port 2 resume error -19
Jan  9 15:16:53  kernel: [  434.246721] done.

etc.

Somewhere between "suspend entry" and "Syncing filesystems" the suspend
appears to be breaking.

Bug description:
  After upgrading to Kubuntu Eoan (19.10) yesterday, my laptop crashes
  after resume from suspending. This is regardless the way of suspending
  (closing lid, selecting suspend from sddm, systemctl suspend).

  The journal shows:
  ferry at chromium:~$ journalctl -b -1 -e
  ..
  sddm[1106]: Message received from greeter: Suspend

  kernel: PM: suspend entry (deep)

  On resume (keypress, open lid) resume starts but immediately crashes
  and reboots.

  The laptop is an Acer 720p Chromebook with Chromium replaced and
  working fine with Kubuntu since 5 years or so.
