I only use the Sidux because they released the shut down patch required to shut down properly on the 2.6.22 kernel line and on two other systems the drives are turned off nicely [standard Debian still runs on the old shut down scripts. On that basis I believe that this is a HP (Intel?) issue not related to any particular distro. - 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/
