Can confirm happening to my reasonably new installation on server 22.04.3.
Server isn't doing much, some dockers and a tp-link omada installation. Have
null'd out the suspend options.
Is anyone else also runing plex, after the soft lockup goes on for long
enough I start getting these in my kern
I am also having the same issue as Andrea/Camille above. I have tried
the work arounds above but have not had any luck. I see there hasn't
been any updates to this so I wanted to say that I am having this issue
as well.

For me it started after installing gnome on my Ubuntu server. Suspicion
is that the desktop sets up suspend mode, though since it is used as a
server it causes issues for any server programs that need to not be
suspended

I troubleshooted some more, and it looks like I may have resolved the issue.
For an unknown reason, suspend/hibernation service was enabled on this server.
It looked similar to this issue here
https://bbs.archlinux.org/viewtopic.php?id=269203, where a race condition
causes CPUs to freeze upon

I attempted a BIOS update and verifying my swap was working properly. Also
reseated my GPU and still no luck.

Taking a closer look at the timing behind the CPU soft lockup, turns out
it happens every 21 minutes, varying between 21min33sec and 21min42sec
for the times I've looked at.

Hi all,
Ubuntu server 22.04.1 is having issues freezing repeatedly with CPU
softlocking. The issue seems to have started in the last week, all
packages are up to date. I've updated to hwe
If you run 'apport-collect 1989521' from the affected system the log
files will be uploaded in a fashion which will be much more usable.
Thanks!
