It appears to have a NULL poiner passed to in_pcballoc.

Boot any FreeBSD 4.2 and above on a machine with lots of memory.

 so it panics, but you don't include the string[1]. it has a traceback,
 but you don't include it. on top of that you provide a way of "repeating"
 the problem that is so obviously ambigious that it couldn't even be
 considered helpful.
 
 
 do you expect someone to even look at this PR or is it just a way to
 get some anger off your chest? if its the latter, let us know so we
 can close this...

 1. in_pcb.c::in_pcballoc() doesn't even have a panic() in it, unless
 something it calls panic()s.

Does this problem still occur? If so, could you provide further 
information such as the panic messages and gdb/ddb traces.
