Errata matter a lot unfortunately - older IDE controllers commonly have bugs where changing the set up of one interface affects the other even if a transfer is occuring. > Do you think the approach is unsafe, even if the piix tune routine is > serialized with a per-driver lock? Bartlomiej? If the documents/errata for the chips are checked then I can see it making sense. I do worry that it may introduce other races because the IDE locking is such a mess but that would be true of any change and eventually has to be addressed. I think it makes sense, with corrections. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
