Synopsis - kernel panic when ipifler work;
hello :)
I have encountered a strange problem in FreeBSD 5.4 - kernel panic when
it(kernel) is compiled with IPFilter. I think so, because with kernel
ipfw this machine works quite well. Panic ususlly occurs after booting
and starting all services.
What can it be?
Here is the of panic message:
"Fatal trap 12: page fault while in kernel mode
fault virtual address: 0xc
fault code: supervisor read, page not present
current process = 27 (swi1: net)
trap number = 12
panic: page fault"
Here is my kernel config:
