error from ntpd upon IPv6 address receipt/bind

[Chris Ross <cross+netbsd%distal.com@localhost>]

  I have all of the machines (except for the router) on my network set up with 
ip6mode=autohost.  With both -current (5.99.29) and netbsd-5 hosts, I see two 
error messages shortly after the machine displays the getty/login banner after 
booting.  I believe this timing matches with when the router advertisement is 
received from the IPv6 router on the network, and accepted by the host causing 
the IPv6 address to be set on the interface.

  These errors/messages are (on my -current box):

May  8 10:01:15 skaro ntpd[357]: bind() fd 28, family AF_INET6, port 123, scope 
0, addr 2001:5c0:1101:420:20d:56ff:fe71:5b0a, mcast=0 flags=0x11 fails: Can't 
assign requested address
May  8 10:01:15 skaro ntpd[357]: unable to create socket on bge0 (7) for 
2001:5c0:1101:420:20d:56ff:fe71:5b0a#123

  I'm not sure what is causing this.  I would expect ntpd to be able to bind to 
that address.  Or is it trying "too early" or something.

  Does anyone else see this?  Am I doing something in an unusual way that 
causes this?

  Thanks.
