Bug#816055: big pause after "Stopped raise network interfaces"

[積丹尼 Dan Jacobson]

Package: systemd
Version: 229-1
Severity: wishlist

At shutdown the screen pauses for many minutes with the last message being

"Stopped raise network interfaces"

upon which I went to the washroom. When I returned the computer had
already finally shutdown.

I suspect that the problem lies with whatever follows that.
But zgrep -i raise /var/log/syslog*
only shows start, not stop. So at that point logging is stopped.
