Maybe back-porting any critical sata_mv fixes to 2.6.16.x is appropriate,
considering that I don't think RH or SuSE will necessarily want to pull
the whole thing.
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.
