yes

Yes.
That's what I did:

boot -gd && gdb -k kernel.debug && target remote /dev/cuaa0

In gdb "bt" only shows two entries. The function where the panic
occurred and 0x0!

BTW, after boot -gd, when gdb attaches I have a kernel panic too.
But I can just enter "continue" and the kernel continues booting.
Is that ok?
