Excellent. I am also changing the title of this thread since it is irrelevant to
the topic at hand.

OK, we are getting somewhere.From what I see you have two interrupt overrides:

(XEN) ACPI: INT_SRC_OVR (bus 0 bus_irq 0 global_irq 2 dfl dfl)
CPI: INT_SRC_OVR (bus 0 bus_irq 0 global_irq 2 dfl dfl)

.. but the FADT has the ACPI interrupt listed as interrupt 9:

[    0.000000] source_irq is 0, global is 2 and FADT is 9

.. well, that would imply that the APIC should be edge, low, but Xen thinks
it is level.

Can you do one more thing - bootup the same kernel as baremetal? Without any Xen
and with the same options .. and also with /proc/interrupts so I can see what 
native
Linux sees?

Thanks.
