Following up on my earlier reported problems with
ffs_alloccg panics, I added debugging to my kernel,
and also enabled options INVARIANTS,
INVARIANT_SUPPORT, WITNESS, WITNESS_SKIPSPIN, and
DEBUG_VFS_LOCKS. After my last panic I now have a
512MB vmcore.0 file in /var/crash.

As mentioned before:
uname -a
FreeBSD mydomain.com 5.2-RC2 FreeBSD 5.2-RC2 #1: Wed
Jan  7 13:39:36 PST 2004    
root@mydomain.com:/mnt/tmp/src/sys/i386/compile/GENERIC
 i386

Now following what I think the FAQ is trying to say,
here is what I get when I use gdb:

gdb -k /usr/src/sys/i386/compile/GENERIC/kernel.debug
/var/crash/vmcore.0
GNU gdb 5.2.1 (FreeBSD)

This GDB was configured as "i386-unknown-freebsd"...
/var/crash/vmcore.0: Unknown error: 0.

No stack.
(kgdb)

What now? Thanks.
