Add the following to your kernel config:
options DDB, KDB, GDB
# Add this if you're using a firewire console
# Do an unattended dump and reboot
Then recompile your kernel. The problem you're going to run into
since the problems you're having seem to be with the ATA code is that
there is a good chance you're not going to be able to dump the crash
dump to disk. I'd highly recommend using a serial or firewire
To setup a serial console just add the following to
your /boot/loader.conf or set it at the loader prompt.
-- Firewire --
For a firewire console you'll need to load the following modules
assuming they aren't in your kernel.
You may need to do a fwcontrol -r on both systems to make sure
everything is in sync.
Once loaded on your client machine, just do a fwcontrol to get the
address of the other system. Then to connect to the server just:
dconschat -t 00-00-0e-10-00-b0-29-d0
Where 00-00-0e-10-00-b0-29-d0 is the firewire address of the server.
