It really appears have not a lot to do with sata_mv, though there's no guarantee there. Tejun -- this is 2.6.32, libata trying to identify a newly hot-plugged drive, and hitting a warning in libata-sff.c. Looks self-inflicted to me! :) Mikael -- any chance you could someday retry this on 2.6.38.2 ?
