I got the same issue, and I don't have a bridge interface, but I do have
a NFS entry in /etc/fstab. Disabling it makes the reboot to succeed.

Given that systemd is now the default, if every persons with an NFS entry
in fstab will get their systems broken, it might be a good idea to increase
the severity of this bug.

This patch works for me, thanks.
