It might also be interesting to disable tagged command queuing 
on the ncr. Something like '/usr/sbin/ncrcontrol -s tags=0'
does this.

I had mysterious lockups on my system (not even the mouse cursor or
keyboard would do anything) and this TCQ disable made this go away
(thanks Stefan for the suggestion).

Admittedly it is not a panic but maybe it makes a difference

(BTW I flashed new firmware on my drive and now TCQ enabled also works)
