Actually, after thinking about it more, I seem to remember that Jason Thorpe over in NetBSD runs an AS200 with a Promise Ultra/33 card. So it might be an srm console issue with this card.. Before pulling out all the stops, I'd first try updating the SRM console, and they try a Promise card.. This is just a WAG though.
