I believe that I've got a similar problem with amdsbwd(4). It needs some resources (I/O ports) that belong to ACPI. The problem is that the driver attaches to isa bus which is under isab->pci->pcib and those particular resources are not assigned to the Host-PCI bridge. I think that you already made a suggestion that perhaps isa bus should directly attach to acpi bus when acpi is available. Not sure if there are any alternative approaches. -- Andriy Gapon
