If that were the case, there might be information about an exit failure in the log. On the next boot, "journalctl -b -1" might have useful info.
I also wonder if enabling sysrq and using sysrq+'t' would help determine which process is stuck:
It might but it's also really verbose, so for starters "systemctl list-jobs" is the path of least resistance I suspect. Report suggests the systemd cylon eye, which suggests a job is running and not exiting as you say, so list the jobs and then do a systemctl status on each one of them to find out what they are up to.
