Hi

Now I have commented out bpfilter, but crashed again. I have 
cronjob which scans our c-class net against back orifice and that 
is what crashes system:

bash-2.02# echo "sweep 194.204.12"| /usr/local/bin/bounix
Back Orifice console client version 1.21
 (Type 'help' for assistance)
BO>Sweeping subnet 194.204.12.*...
 194.204.12.1 -- 194.204.12.32
 194.204.12.33 -- 194.204.12.64
 194.204.12.65 -- 194.204.12.96
 194.204.12.97 -- 194.204.12.128
 194.204.12.129 -- 194.204.12.160
 194.204.12.161 -- 194.204.12.192 <- here we crashed...

after that I get:

MP_LOCK = 01000002; CPUID=1; lapic.id=0c000000
FAULT VIRTUAL ADDRESS = 0x13
FAULT CODE = supervisor read, page not present
...
...
...
...
CURRENT PROCESS = idle
INTERRUPT MASK = <-SMP: XXX
KERNEL: type 12 trap, code = 1

Doesn't look like softupdates ??? Below is my kernel config file... maybe someone has any idea...
