Some/all of the older ones cannot (errata). So, I've done the one-liner change in sata_mv, to add ATA_FLAG_AN to the 7042 and 6042 chips, and it all seems to work rather nicely. Am I missing something? Is there any other local code to sata_mv that should be provided before setting ATA_FLAG_AN ? Like I said, it works, but I just want to check whether any other pieces are expected to be present? Cheers Mark
