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
