Interrupt using all the CPU

[nocturnal]

Hi

I'm sorry for the second e-mail but the uname is.

FreeBSD unix.swebase.com 5.3-RELEASE FreeBSD 5.3-RELEASE #0: Fri Nov  5 
04:19:18 UTC 2004 
root at harlow.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  i386

We haven't even recompiled the kernel since the install. It was supposed 
to be a temporary machine but turned into a development machine for me 
and some other developers.
