After some googling, I see that dumpdev can be set as a variable in the
bootloader (this should be added to the help for the "set" command" in
the loader, imho).  I rebooted, dropped to the bootloader command
prompt, set that variable to /dev/ad1s2b (my swap device) and rebooted.

When I got to the debug prompt, I ran "panic" to cause a panic.  All I
got was the following 4 lines repeated over and over and over :-)

panic: assertion: gd->gd_vme_base != NULL in vm_map_entry_kreserve
mp_lock = 00000003; cpuid = 3; lapci_id = 07000000
boot() called on cpu#3
Uptime: 16s

The values change, as does the cpu#, but that's the error.

Am I missing some step in getting this core file?
