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.
