A computer that is running an x64-based version of Windows Server 2003 may stop responding when you try to synchronize PCI devices

A computer that is running an x64-based version of Microsoft Windows Server 2003 may stop responding when you try to synchronize Peripheral Component Interconnect (PCI) devices that control printers, copiers, or press interfaces.

This problem occurs when interrupt requests conflict on a device driver that specifies the highest DIRQL value in the SynchronizeIrql parameter of the IoConnectInterrupt routine. This conflict results in an unreported deadlock condition.

Windows multichannel digital printers, copiers, and press interfaces rely on the value that is specified in the SynchronizeIrql parameter.
