Only for devices that have fixed addresses. This wouldn't be true for devices on the PCI bus, where probe order could affect the resources assigned to a given device. The only real way for self-enumearting busses are a bus-specific address. : When you need to pinpoint a device : prior to any form of bus enumeration, the unit number is meaningless : and any mechanism that includes a unit number is bogus. That's why : hints are the wrong tool for pinpointing a console or debug port. Agreed. Warner
