Both oops in nmbd. Looks like neigh->ops is wrong in
if (neigh)
return neigh->ops->resolve(eth->h_dest, skb);
After each oops the machine was totally dead for 50-60 seconds, no
response to magic keys. Then it responded to the magic keys and wrote
to syslog but was still basically dead, no input, VT switch nor network
response. CTRL-ALT-DEL accessed the disk but did not shut down, only
power off worked.
