This is unavoidable. Two drivers grabbing the same PCI I/O range is dangerous. Now that libata supports PATA, it would be easier to let libata support both SATA and PATA. Since that is a single driver, it makes DMA easy to support for both SATA/PATA. If libata does this, there needs to be a "ide=disable" or "legacy_ide=libata" switch added somewhere, for the cases (most distros) where IDE driver is built-in. Jeff
