ipfw: -1 Refuse ICMP:0.0

Hello.  I'm getting the following line:

   ipfw: -1 Refuse ICMP:0.0 <router-ip> <my-ip> in via <my-interface>

ten times and then my computer locks at startup.  I was using
fixed IP addresses, I enabled DHCP and I just got the above.

I realize that -1 is a rule that you can't turn off that
rejects invalid packets (due to offset errors?).  Anyway,
my question is... what I can do; I'd like to use DHCP and 
ipfw but the result above seems to be reoccurant.  I rebuilt
the kernel once more (only adding options IPFIREWALL, 

Any ideas?
