Hi Bart,

please take a look at the OOPS below, seems like we BUG() in ide_intr() at
BUG_ON(!hwif->handler) which shouldn't happen. Full message is at:

http://www.gossamer-threads.com/lists/linux/kernel/1077445.

It is 2.6.29.3 with both PIIX_IDE and ata_piix compiled and it could be
that those two step on each other's toes, but this is only wild stab in
the dark.

I'm sure you have more ideas.
