Adding 'noapic' to the boot command line makes the machines work correctly. As far as my problem goes this is a fine solution. The afflicted machine just holds a couple terabytes of nearline storage and has no performance demands to speak of. I will replace the ieee1394 hardware and verify that it works. I expect sucess now. I have six of these machines and am holding one out as a spare. I will be happy to continue testing and prodding on that spare unit.
