To summarize: libata, prior to 2.6.22rc1, lacked the feature to spindown the hard disk. The last discussion was about who's responsable to issue the STANDBYNOW command to the hard disk. Response from the discussion is: the kernel. Trying to issue it form userspace (iff your shutdown(8) implementation do so) will now result in a big fat warning, until these compatibility measures will be dropped from the kernel (soon or later). - 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/
