This is with one of the ATA - macio parts, I assume? Could you tell me whether (a) the two are on the same ATA bus, (b) the name of the ATA controller in OF (i.e. ata-3 or ata-4), and (c) which modes the driver wants to configure for both devices? I wish I had more hardware to test this on... -Nathan
