Send patches. We also probably want to change speed straight from UDMAlots to UDMA33 if the cable is CBL_UNK so that we can rapidly recover in the cases where the controller says "I'm crap I don't really know" (eg ATI and Nvidia without ACPI) - 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/
