...which presumably stops working as soon as there's a non-ATA SCSI device in the system. (It worked for me, I think, but there really ought to be a generic solution.) Again, what's apparently missing is a map between ata ports/links/devices and scsi hosts/targets/devices. --Andy -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
