Because on at least some kernels hda=noprobe ... etc does not stop the old IDE layer grabbing the PCI device and continuing to claim ownership (which means ATA cannot attach to it). Arguably this is correct behaviour as the IDE layer was asked to ignore the devices *NOT* to ignore the controller. Alan
