Title:
  systemctl suspend stopped working: laptop immeadeately wakes up again

Status in linux-signed-hwe-5.11 package in Ubuntu:
  New

Bug description:
  I always suspend my laptop using `systemctl suspend`. It worked for a
  year as expected until today.

  Buggy Behavior: after `systemctl suspend` the seemingly usual suspend
  happens, however the laptop wakes up immediately. Things get more
  weird from here, as I need to input my password twice to get back into
  GNOME.

  Troubleshooting I did:
  1. apt update && apt dist-upgrade 
  2. Disabled nvidia-suspend.service, nvidia-persistenced.service, 
nvidia-resume.service
  3. Booted with an earlier kernel version where it used to work: `5.11.0-40`, 
`5.11.0-38`
  3. Detached all devices, and the power cable
  4. Rebooted into a separate user that has no tweaks, gnome-extensions etc
  5. The issue persists -- I attached relevant parts of `journalctl`: from the 
time when I used `systemctl suspend` till a minute or so after I logged back 
into GNOME.
