Description Karl 2012-03-21 11:51:15 UTC

Any drives connected to the Marvell 88SE9172 (on a gigabyte GA-HA65M-UD3H-B3 motherboard) do not appear to be recognised by default - it seems that the ahci driver does not recognise the pci vendor/product ID.

Adding the IDs by sysfs and it *seems* to work - 
echo 1b4b 9192 > /sys/bus/pci/drivers/ahci/new_id

It also has a "RAID mode", but I'm pretty sure it's just a form of dmraid.

My apologies if this is logged to the incorrect place, or if I should've gone to my distros kernel team first.
