That _should_ have been fixed in the last update to ata_piix. If you could get Stuart to re-test and re-submit that patch if necessary, that would be useful. Geert, two things to try: 1) Try the latest kernel 2) Fiddle with BIOS settings until your PATA and SATA devices appear as _separate_ devices on the PCI bus.
