Are you certain you have crashdumps configured properly? If you break to DDB and 'call doadump', does it dump and savecore? If yes, then you'll at least need to transcribe the instruction pointer from the system console when the system panics (e.g. remove KDB_UNATTENDED so that it doesn't automatically reboot after the panic so you can copy it down, or set up a serial console and log the panic output there).
