Look back in the archives for my messages on this. Basically, trying
to use the pata_hpt37x driver on an Rocket133 card (HPT302 Rev 1 chip)
fails with a bunch of errors shown below. This is a PCI add-on card
with /home and /local filesystems on there, mirrored across a pair of
120gb WD drives. The system also has a pair of builtin SCSI
controllers (AIC7xxx) which hold the OS filesystems, as well as a tape
drive for backups. It's an SMP system. I guess I should try to boot
it up UP and see how it goes then as well.

I've tried booting 2.6.18-rc4-mm3 with the irqpoll option, but it
didn't make a difference.

Do you need more details?
