I'm a bit confused by this one. It's true devd now starts earlier and
could start before network_ipv6, but it starts after netif and you
have an IPv4 address configured so it should be up by the time devd
starts up. One possible issue is that the current check is bypased if
grep isn't available (say if /usr is an nfs mount). If that's the case
for you, the following patch may fix things.
The other thing I can think of is that there's a delay in the interface
transitioning to the UP state. If that's the case I'm not sure what
the answer is. We might need to use something else to de-bounce
the interface configuration. It might be worth a try to modify
etc/rc.d/devd to run after network_ipv6.
