There is nothing to correct.

Error Code 22:
See MS KB 272291 - "ACPI IRQ Holder for PCI IRQ Steering" Problem Device Entry
in System Information Tool" (http://support.microsoft.com?kbid=272291) where
you will find it stated that what you are seeing is "by design".

This problem is often the result of having changed the layout of your PCI
cards or following the removal of a card.  Forget about this "error" as it is
unlikely to have an effect and is simply indicating that the place holder
previously used is no longer required.
