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?
