I'm having an issue shutting down.  Fedora 34, just updated to 35, same problem.  (It was around in 33 as well, I've been putting up with it.)  I know that there is another list for beta versions, but this issue was there in the current version as well.

Somewhere around 1 out of every 10 shutdowns,  the system goes down to 
"[ OK ] Reached target System Shutdown", but then, 
"[ *** ] a stop job is running for Cryptography setup for luks-<cycle through LUKS volumes>"

It typically goes for about 1/2 hour if I don't get fed up, and hold the power button down.

I just saw after that 1/2 hour:  
[Time] Timed out starting System Reboot
Forcibly Rebooting: job timed out.
audit: type=1334.........

I still had to power it off.  On reboot, it seems OK.


I haven't found anything interesting in /var/log/messages regarding it.

Any suggestions to further troubleshooting?

Thanks,
