The problem appears to be having more than 2 Promise cards in the system. Both machines have >2 cards (one has 3 and the other has 4) and they both lock up on shutdown in the same fashion (first 8 drives are ok, then it locks). Between this and the intermittent BUS Errors under load, perhaps I toss the promise cards and upgrade to some 4 port SIL cards instead.
