We also need ACPI, where available, because that's the only way to obtain a BIOS-set hard drive password. And BIOS vendors often deliver hard drive-specific errata this way, if the problem is serious enough (though certainly we would prefer that the OS knows about drive errata, when a runtime patch is necessary) Jeff - 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/
