There is deep magic to beware of in the IDE case. I recently fixed this for 2.4 (and sent Linus a patch for 2.5). If the IDE controller channels are in legacy mode then the IRQ is 14/15 and ISA style. In that case we shouldn't be looking up the IRQ line in the ACPI and PC BIOS cases at least. For some non PC platforms it may be more complex ------------------------------------------------------- This SF.net email is sponsored by: Etnus, makers of TotalView, The debugger for complex code.
