Shutdown taking forever - possibly due to NM?

Hey guys. For the past few weeks to months, the system has been taking absolutely forever to shut down via the `reboot` command.
Symptoms:
Black screen immediately after command, then nothing for many seconds until a TTY interface appears briefly before shutting down fully.
It usually contains a varying amount of ^@^@^@^@^@^@^@s and "watchdog did not stop" (I think!), sometimes including something else that I can't usually read in time.

journalctl log:

Re: Shutdown taking forever - possibly due to NM?

Please post your complete system journal for the boot:

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st

But it looks like you're attempting to get a new netwrok connection during the shutdown…
