I think the 1st message on this thread holds the answer:

Looking at your acpidump in
http://bugzilla.kernel.org/show_bug.cgi?id=8283
clearly the 2nd table is broken (it is missing the SCI override)
and that is why you get no ACPI interrupts.
If Windows works on your machine -- ACPI events such as power button etc --
then that is proof that Windows doesn't use the 2nd MADT and I need
to revert 09fe58356d148ff66901ddf639e725ca1a48a0af
