Thanks, that fixed the panic and the system boots.  Now it is
complaining about AE_AML_BAD_RESOURCE_LENGTH and still unable to route
IRQs, but it definitely looks better than the ACPI parsing errors in 9:

pcib0: allocated type 3 (0xdffff000-0xdfffffff) for rid 10 of pci0:0:10:0
pcib0: matched entry for 0.10.INTA (src \_SB_.PCI0.AUBA:0)
pci_link26: Picked IRQ 20 with weight 0
pci_link26: Unable to route IRQs: AE_AML_BAD_RESOURCE_LENGTH
