While this doesn't help your situation any, I can say that I have also seen
the same kind of interrupt errors on a VIA chipset motherboard (it was an
Athlon, but had a VIA ATA100 controller) and they happened every time it
booted. It would immediately downgrade everything to PIO right after
detecting the hard drive, if I remember correctly, even though that drive
worked fine in other machines. I believe this to be a bug with VIA ide
controllers, or if not with the controllers themselves, in the driver for
them.
