Bug#873613: systemd gets confused at shutdown time

[Harald Dunkel]

Package: systemd
Version: 232-25+deb9u1

At shutdown time systemd just shows a message saying

	watchdog: watchdog0: watchdog did not stop!

for 5 minutes :-(.

If I boot without quiet, then systemd reveals that it gets 
confused by service dependencies, nfs mount points and 
probably some virtual block devices (mdadm, lvm2, crypt, 
etc). Basic problem seems to be indicated by the message

	nfs: server nfs-home not responding, timed out

pretty late at shutdown time. 90 secs before it tried to 
unmount the local mount points. Apparently it ignored NFS
completely. No wonder that it got stuck.

Would you mind to check and fix for stretch? 


Thanx in advance
Harri
