(This is weird; function 0 > is supposed to be the ISA bridge!) Given that pre PIIX3 devices (MPIIX and PIIX original) never worked in the old IDE code (well sometimes semi-worked by accident because the BIOS values were right and they didn't break anything) I wouldn't draw any conclusions. > PCI_DEVICE_ID_INTEL_82801DB_1 == 0x24c1 (ICH4 device 31 function 1) > > piix seems to treat this the same as most other ICH PATA interfaces, > which are handled by ata_piix. > > Does anyone know why these aren't handled by the libata-based drivers? I don't know about 0x24C1 however it isn't listed in the Intel ICH programming manual so given we've also had no reports about it I suspect it's an error in the PIIX driver ?
