Run tcpdump without any options/arguments. If I do something like specify

 I tried on this on another 6 stable machine I have from the same date and
 it doesn't exhibit the problem. Perhaps this is due to the number or types
 of interfaces on the machine? The working box has only dc0 while the box
 that panics has em0 and sis0-3.

 Please obtain a full traceback per the instructions in the kernel
 debugging chapter of the developers handbook.
