Hi,
I am using FreeBSD 4-Stable with cvsup up to 3-June-2003 HKT. I am testing =
with the netgraph modules (one2many and fec). While testing them, I have =
changed the ipaddress ifconfig and load kernel module (one2many/fec) and =
use ngctl command repeatly. I know I should not run the command or load m=
odules repeatly but somehow I get kernel panic.
Now I get a back trace with the core dump:
