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

[Klaus Rombach]

Hello, everybody.

My notebook (ThinkPad T530) apparently goes into sleep mode according to
the log (see below). In reality it hangs up: The screen (backlights)
stays on, but shows no content (black image). The device can't be woken
up anymore. I have to switch it off (Power Off for 5 sec.).

The problem occurred immediately after upgrading Kubuntu from version
19.04 to 19.10. The system was put into operation years ago with version
14.04 and has not been reinstalled since then, but has always been
upgraded to the next version by "do-release-upgrade".

Title:
  Reboot after resume from suspend (deep)

Status in ubuntu-release-upgrader package in Ubuntu:
  Confirmed

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
  ..

  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.
