New Intel IDs aren't being added to ahci because ahci controllers have their own PCI class ID (0x010601) which ahci can key off. Apple seem to have declined to program yours as an ahci device - it's still claiming to be an IDE device (0x0101), and so ata_piix is the correct driver to be using.
Of course, this ignores the fact that in reality we'd prefer to use ahci. The "easiest" way to do this would probably be to add a PCI quirk that reprograms it, but Apple seem to have declined to provide an Apple subsystem ID to key off and argh it hurts. -- ata_piix used instead of AHCI for Mac Pro https://launchpad.net/bugs/96692 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
