I had an awful time trying to keep an box with a i82801BA
(attached to a i82815) stable when used with raid(4).
Heavy disk activity (such as checking the mirror) would
hang the thing. This was a cyclic problem that only
seemed to get worse.
I gave up and only use that board for occasional testing and
development now. This was with NetBSD 3.x.
