Without answering your specific question, just remember that sata_mv is considerly "highly experimental" right now, and still needs some workarounds for hardware errata. For now, the goal is a system that doesn't crash and doesn't corrupt data. If its occasionally slow or spits out a few errors, but otherwise still works, that's pretty darned good :) Jeff - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
