I followed the freebsd kernel debugging manual, and got some output, but I have no idea what to do with it. The only thing I think I understand of it that the bit that matters are just the two last lines. Is there anyone that can help? # kgdb kernel.debug /var/crash/vmcore.2 GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
