Yes. It crashes on current too. In pfattach(). Also, loading ipfw and
ipfw_nat causes panics in ipfw_init() and ipfw_nat_init(). Although
this can be easily bandaged with CURVNET_SET(vnet0), it rather reveals
problems with these modules.

E.g. currently in ipfw_nat_init() we lock virtualized layer3_chain in
vnet0 context, I think, to restrict the access to ipfw_nat_*_ptr
variables during modification. But the access is not protected from
another vnets, which might already exist at the moment when ipfw_nat
is loaded.
