Yes, windows XP could handle better the power button pressed event (causing the hd not to go to emergency parking, even when forced shut-down, most of the times). But regarding a normal shut-down cycle, isn't this a regression? You don't solve a regression adding a feature (IMHO). - 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/
