Also note that when the '-X' switch is omitted (i.e. one only issues "/usr/sbin/hdparm -d1 /dev/hdX"), the driver sets up a mode that doesn't work and then quickly falls back to PIO. - 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/
