It's strange that ACPI doesn't make a difference; usually when it comes to interrupt routing, either the mptable or ACPI are hosed, but not both. This wouldn't happen to be a Dell workstation, would it? I had a very similar problem with my Dell, and wound up having to hard-code some of the routing. At this point I'd recommend contacting John Baldwin. Scott
