I am testing with the netgraph modules (one2many and fec ). While testing them, I have changed the ipaddress using ifconfig and load kernel module (one2many/fec) and use ngctl com mand repeatly. I know I should not run the command or load modules repeatly but somehow I get kernel panic. Now I get a back trace with the core dump: Script started on Tue Jun 3 10:37:30 2003 fw# gdb -k GNU gdb 4.18 (FreeBSD) Copyright 1998 Free Software Foundation, Inc.
