That's probably why. To use AHCI you need to set it to RAID mode. Having done that, you can still use the drives independently if you prefer kernel RAID; you just have to go into the BIOS RAID setup and set the drives to JBOD mode (or something like that), by telling it to remove all RAID information from the drives.
