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.
