The current logic to init the local APIC and the IO-APIC does init the
local APIC LVTERR/ESR before doing any sanitation on the IO-APIC pin
configuration. It's already noted on enable_IO_APIC() that Xen
shouldn't trust the IO-APIC being empty at bootup.
At XenServer we have a system where the IO-

The issue that this patch attempts to address is S3 related.
Currently, suspending a XEN guest multiple times does not work.
This happens because PIIX4 PM io space gets unmapped during S3
resume and any accesses performed to trigger subsequent suspends
are not handled. So, the guest spins on the wa
