Is there a macro for dumping information about Resource or Resource->Data? Here's what I have for now at sys/contrib/dev/acpica/resources/rscalc.c line 237: pcib0: matched entry for 0.10.INTA (src \_SB_.PCI0.AUBA:0) pci_link26: Picked IRQ 20 with weight 0 rscalc.c:237 Resource->Type: 7 Resource->Length: 0 pci_link26: Unable to route IRQs: AE_AML_BAD_RESOURCE_LENGTH All of the errors are from there and look identical (Type 7, Length 0). Type 7 appears to be ACPI_RESOURCE_TYPE_END_TAG. -- Benjamin Lee http://www.b1c1l1.com/
