This looks like something tried to use a psref target -- i.e., an
object that you can acquire psref to, in this case a struct ifaddr
object -- after it was destroyed with psref_target_destroy, or
possibly before it was initialized with psref_target_init.

I don't know what to make of the peculiar circumstances in which it is
triggered, though.  I have no idea how ne(4) or anything else on the
network stack's ifaddr maintenance on amiga might be different from
ne(4) at pcmcia on another architecture.
