I would like to see the output, next time you can get it. The thing with the 6041 chip, is that I actually have all of the Marvell documentation and errata info for the chip. So in theory, we know everything about it, and there are no secret failure modes yet to be discovered. The sata_mv driver does not depend on the board's BIOS for anything either. That's the theory, anyway. :) Cheers -- 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/
