Could be some kind of SATA PHY quirk or incompatibility that only shows up in AHCI mode or something. It seems from the output that the SATA link may be going up and down. You could try forcing 1.5Gbps (libata.force=1.5Gbps if libata is built in, or force=1.5Gbps when the libata module gets loaded) and see if that helps. Maybe Tejun has some more ideas.. > 2.
