how to find what hangs rebooting

by

During reboot my machine hangs on 

[ OK ] Removed slice system-postfix.slice

I don’t know if problem is with postfix (guess not, because of [ OK ]), but how to find what is next service (which hangs I suppose)

It’s still alive – I can keep pressing Ctrl+Alt+Delete and get:

[447.012345] systemd-shutdow: 35 output lines suppresed due to ratelimiting
[447.012346] systemd-shutdown[1]: Sending SIGTERM to remaining processes...
[447.012347] systemd-journal[175]: Received SIGTERM from PID 1 (systemd-shutdow).

Then it freezes for about 90 seconds (suppose DefaultTimeout from system.conf) and then finally reboots. This happens on both systems I’ve upgraded to Jessie.
