I confirm I have the same issue on 9.1 r247912 , as below:

Clearing /tmp (X related).
Updating motd:.
Starting ntpd.
Mar  8 14:57:23 pf1-drt ntpd[938]: bind() fd 23, family AF_INET6, port 123, scope 2, addr fe80::90bd:54ff:fe55:2d21, mcast=0 flags=0x11 fails: Can't assign requested address
Mar  8 14:57:23 pf1-drt ntpd[938]: unable to create socket on vlan12 (3) for fe80::90bd:54ff:fe55:2d21#123



However, ntpd runs fine and is bound to the following addresses:
