I finally found the problem, it was not a kernel bug, it was dhcp client.
In /sbin/dhclient-script, it tried to install a route from localhost to
the ether interface, which was bogus if the loop-back interface was not
configured. Under BSD4.4, there's no need to add such a route, it will be
automatically generated by the kernel. So the simplest solution to this
problem is to delete all `route add xxx 127.0.0.1' statements from the
script.
