Agreed -- in theory -- but I'll let Mark Lord or somebody else do that, if they are motivated. sata_mv is labelled "HIGHLY EXPERIMENTAL" for a reason :) Its a known bug report generator, with bugs far outpacing fixes at present. Key patches to backport or test, in priority order, would be: [libata sata_mv] do not enable PCI MSI by default [libata sata_mv] add 6042 support, fix 60xx/50xx EDMA configuration [PATCH] Add missing FUA write to sata_mv dma command list After that, you're at the mercy of not-yet-worked-around hardware bugs, and (as Mark Lord appears to be finding) some driver bugs as well. sata_mv development slowed to a trickle for a long time, after the original developer disappeared, and I didn't have time to dig deep into the hardware details. Mark Lord recently started picking up the pieces, so things are looking much better already. I have another patch from Mark to forward to you and 2.6.16.x (stable@), coming to you today.
