If there's a url for this, please let me know. This is probably a better candidate for -hackers, so I've moved it there. You have a basic problem that you can't take a dump until you have a dump device. If you panic before that, you're limited to ddb or serial gdb. There's some stuff in the online handbook about how to set up serial gdb, and in LINT about how to set up ddb. Note that the flags for the serial device have changed in *some* versions of FreeBSD, so check your LINT file for the correct flags.
