[Bug 2084252] Re: 6.11.0-8-generic: system fails to wake up from suspend

Are you sure it's kernel? Or that's just a first guess? This could
easily be the systemd bugs.

You could try SYSTEMD_SLEEP_FREEZE_USER_SESSIONS=false to see if it
helps.

Bug description:
Since I upgraded to oracular my system won't wake up from suspend
anymore. Unfortunately I also don't see anything helpful in the logs.
Some of the last messages I am seeing:

On wakeup the fans spin up, power seems to come back since the
keyboard LEDs turn on but the screen stays black. It is not only a
screen issue since I also can't log in via ssh or otherwise get it to
respond via network.
