Ok. IIRC, early revs of dino mostly had problems with nested PCI-PCI
bridges. I'd need to review the dino errata and I don't have that with
me here.

hmm...the newer PDC isn't programming Dino or anything

should just give up trying to walk the bus at this point.
I suspect that's crashing the box later.
