DDB

I have compiled my kernel with options SMP and with following
options in hope that I will be able to drop into debuuger
after fatal trap 12 (FreeBSD-5.4-STABLE). I have added following
lines to my config:

options         KDB
options         KDB_TRACE
options         DDB

Although dmesg | grep SMP says
FreeBSD/SMP: Multiprocessor System Detected: 4 CPUs
SMP: AP CPU #3 Launched!
SMP: AP CPU #1 Launched!
SMP: AP CPU #2 Launched!

top shows that processes are running only on CPU's 0 and 2.
systat also shows:

root     idle: cpu0 XXXXXXXXXXXXXXXXXXX
nobody        squid XXXXXXXXXXXXXXXXXX
root     idle: cpu2 XXXXXXXXXXX
root      swi1: net X


Is this normal, or am I missing something?

Regards,
Goran Gajic
