Maybe we need a hack to return -ENODEV iff ahci is > there to handle the device. I can verify that just loading ahci before ata_piix is successful, and udev will load both of them since the PCI IDs match. So just having ata_piix refuse to bind would solve the problem. Unfortunately I can't see a way of doing this only if ahci is present if they're modular... -- Matthew Garrett | mjg59@srcf.ucam.org - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
