[ 151.130176] watchdog watchdog0: watchdog did not stop!

disable your watchdog?

There is a interval from 84 sec to 151 sec, so I suppose there is something wrong with journald.

Interesting hypothesis given that the journal comes *after* the hang. There's either a misbehaving watchdog or a hanging process on shutdown.

The problems is journald. It seems journald takes too much time to write journals to the disk. After I disable journald by setting Storage=none in /etc/systemd/journald.conf, the shutdown finished very quickly. Assuming that too much write is harmful to SSD, disabling journald is not a bad idea to my netbook, I think.
