Hello, I don't know if anyone else has been experiencing ACPI disable IRQs (specifically IRQ 9) but there seems to be a serious regression recently which causes me grief:

I note, I do use VirtualBox, but unless it's somehow causing the usb hub/yenta socket or e1000 devices to go haywire, I would discount it's relation to this.  If you think otherwise, I can certainly disable it.
