  I had realized that bringing the interface up was the trigger for the panic.
An interesting thing, given the above, would be to note whether using
a static IPv4 address (i.e., not DHCP or SYNCDHCP which is what I have),
or whether disabling IPv6 or IPv6 accept_rtadv would make any difference.

  I?m guessing it won?t matter, but I also have a similar config in my rc.conf,
so testing a wider variety of configs might be of value.

To answer the question...

If you take out the IPv6 configuration it doesn't panic!

(I updated the bug with this information too.)
