My motherboard is an ASUS P6T Deluxe > V2, with the Marvel 88SE61XX ATA controller. My first suspect would be power - that's a drive dropping off the link by the look of it. One thing you could try is swapping the cables over (first the SATA and then the power) and seeing if the problem moves with either. Do you get other errors (in particular a message about resetting) just before the link down error? > Would deselecting the pata_marvell likely get rid of this problem? The > descriptor says: Probably not. The Marvell situation is this (ignoring Jeff's devel driver whose state I'm not sure of) PATA_MARVELL - can drive SATA and PATA ports but without all the extra features AHCI - can drive Marvell SATA fully featured but not the PATA at all. The kernel tries to select the AHCI driver if it sees no PATA drive is present. So you can turn it off on a SATA only box but I'd expect no change. > As I look through kern.log I see that the numbering on the ATA channels is > not always consistent.
