I booted with 'apic=debug' in case this is useful to find out what's
wrong.
dmesg of 2.6.11.6 with ACPI enabled, APIC enabled, 'apic=debug':
http://www-personal.engin.umich.edu/~wingc/apictimer/dmesg/dmesg-2.6.11.6-acpi-apicdebug
(clock runs at double speed)
dmesg of 2.6.11.6 with ACPI enabled, but disabled for PCI routing, APIC
enabled ('pci=noacpi apic=debug'):
http://www-personal.engin.umich.edu/~wingc/apictimer/dmesg/dmesg-2.6.11.6-nopciacpi-apicdebug
(system hangs when loading SATA driver)
One difference I see between ACPI IRQ routing and 'pci=noacpi' is this:
(with ACPI IRQ routing)
..TIMER: vector=0x31 pin1=2 pin2=-1
(with 'pci=noacpi')
..TIMER: vector=0x31 pin1=2 pin2=0
so it would seem that mp_irqs[] differs between the ACPI case and
'pci=noacpi' for mp_ExtINT.
