I also have such a system, and I do have and entry like:
(XEN) ACPI: INT_SRC_OVR (bus 0 bus_irq 0 global_irq 2 dfl dfl)
On the Xen log. I've added some more debug info to my build with the
following patch:

And it does print the following when setting up the iommu:
(XEN) ioapic 0 pin 0 not masked
(XEN) vec=00 delivery=ExINT dest=P status=0 polarity=0 irr=0 trig=E mask=0
dest_id:00010000
I wonder, shouldn't all pins of all the io-apics be masked at boot?
Full Xen boot log below.
Thanks, Roger.
