SYMPTOMS

When you use the Microsoft System Information tool (Msinfo32.exe) to view problem devices in your computer, entries for "ACPI IRQ Holder for PCI IRQ Steering" may be listed. This may occur even if IRQ steering is working correctly. The entries may look like:

ACPI IRQ Holder for PCI IRQ Steering ACPI\*PNP0C0F\00000003 22
ACPI IRQ Holder for PCI IRQ Steering ACPI\*PNP0C0F\00000005 22
ACPI IRQ Holder for PCI IRQ Steering ACPI\*PNP0C0F\00000006 22
ACPI IRQ Holder for PCI IRQ Steering ACPI\*PNP0C0F\00000007 22
ACPI IRQ Holder for PCI IRQ Steering ACPI\*PNP0C0F\00000008 22

These entries represent ACPI Holder for IRQ Steering data structures that did not start (error code 22).

CAUSE

This behavior can occur if you change hardware in your computer and the IRQ holder is no longer required. IRQ holders for PCI steering are listed with error code 22 when they are not in use. Although IRQ holders for PCI steering that are not in use are not displayed in Device Manager, the System Information tool displays them.

STATUS

This behavior is by design.
