Many blessings to you!
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.
For reference I now have...
