We can probably reduce the msleep(150) sprinkled about the code to msleep(100), for the dumb-ATAPI-device wait. - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
