Different Sven here.

I have hit the same bug, but with the Debian kernel 4.7.0-1-amd64 #1 SMP
Debian 4.7.2-1 (2016-08-28).

For now I have downgraded to 231-9 from testing, which works fine. I
will try to gather the debug logs later (not in front of the system
right now and I don't want to brick it remotely), but I see a
systemd-tty-ask-password-agent process while systemd-udevd hangs:

root     3284988  0.0  0.1   8536  4308 pts/11   SN+  11:47   0:00
systemctl restart udev.service
root     3284989  0.0  0.0   6788  1852 pts/11   SN+  11:47   0:00
/bin/systemd-tty-ask-password-agent --watch
root     3284990  0.0  0.0  14472  3204 ?        Ss   11:47   0:00
/lib/systemd/systemd-udevd

The same also happens with systemd-networkd. If I try to start/restart
it, I get the same systemd-tty-ask-password-agent process while
"systemctl start systemd-networkd" hangs.

Grüße,
Sven.
