 There is an entry in your DSDT that is causing this failure:
 
                  Device (DOBA)
                  {
                      Name (_ADR, 0xFFFFFFFF)
  		    [...]
 
 The upper and lower 16 bits are passed, unchecked, to pci_make_tag in 
 mpacpi_derive_bus. Can you try the following patch?
 
 Cheers,
 Jared
