kernel panic

Sorry I can't really help. I get the same thing after setting up my
vonage VOIP adapter. I did a tcpdump on the interface and saw that I was
getting a lot of UDP traffic. I updated my box as of last night and now
I don't get a panic anymore but the box just locks up instead w/out
panicing. I'm using ipnat and ipf w/ basically no ipf rules and only a
generic map for my nat. I tried recompiling ipnat and added 1000 to the
number of states to keep and it didn't help one bit.
Any help would be appreciated. I don't think my file systems can take
many more of these power cycles. But I'll help any way I can. I haven't
really done any kernel tracing or anything like that but if someone can
point me to a what I need to do I'll do it.
