Just so Julian doesn't get blamed here, I was the one who wrote
the Olicom "oltr" driver and made the arp changes. Julian was
just nice enough to commit them.
The only thing I can figure, as I can't tell exactly what caused
it to punt, is that you received a token-ring arp packet that is
somewhat damaged. Is there a token-ring<->ethernet bridge on
your network?
What was it doing in in_arpinput when it panic'd?
