The ACPI routing tables are a description of the underlying hardware
configuration. If you have not also changed the hardware configuration
then you may well have an invalid ACPI table now. If interrupts are
still working with an invalid ACPI table then it probably means the
device is using MSI(1), so all this worry about interrupt assignments is
a waste of time.
Also please always reply to the list.
