Sorry, had to restart. I tried "netdump -s someIP -g someGateway which 
forced netdump into a loop (of requesting ARP for someIP and failing) 
and couldn't stop it.

I only have the photo of the crash itself which ends at and sleepq_add 
before going to panic. I can hardtranscribe if it might be of any use.
