I disagree.  It's very clear what the alignment requirements are on 
amd64 and that acpi-ca is being too strict, harming an actual 
implementation.

Yes, I agree that this alone doesn't fix it.  This looks to me like the 
pci_link code is pointing the interrupt source at the wrong part of the 
resource descriptor.  Perhaps it is not incrementing the pointer 
correctly for 64-bit arches.
