It gets stuck with below message.

How reproducible: Always. 

Steps to Reproduce:

2. Configure tang/clevis to  automatic unlocking for luks device during boot.

3. Here is the content of /etc/crypttab
~~~

~~~

I also noticed same issue with rhel 8.8 

System reboot hangs at “A stop job is running for /dev/mapper/<luks_map_disk>" where unmounting of encrypted volume got hang at boot process. But it works fine if we power off /power on the machine.


Tested with version systemd-239-68.el8_7.4.x86_64 and works fine

Does it occur even if the filesystem on the container is not mounted before reboot? If not, please share the full, exact fstab entry, or, even better, the systemctl show output for the corresponding mount unit? (Just the Before= line would do.)
