Interrupts that come from a PCI device that uses a Windows NT 4.0-style driver are ignored in Windows Server 2003, Windows XP Professional, and Windows 2000 (824395)


The information in this article applies to:

  • Microsoft Windows Server 2003, Standard Edition
  • Microsoft Windows Server 2003, Enterprise Edition
  • Microsoft Windows XP Professional
  • Microsoft Windows 2000 Professional
  • Microsoft Windows 2000 Advanced Server
  • Microsoft Windows 2000 Server

SYMPTOMS

A computer that uses a Microsoft Windows NT Server 4.0-style device driver for a PCI device may lose interrupts from the device, and the device may not work correctly.

CAUSE

This problem occurs because there is a code defect in the PCI bus driver (Pci.sys) that provides the required resources for the PCI device. As a result, the PCI driver does not allocate the correct interrupt request (IRQ) resources, and the Interrupt Service Routine for this device does not detect the interrupt.

MORE INFORMATION

PCI bus drivers and the hardware abstraction layer (HAL) handle the resource allocation for Windows NT 4.0-style drivers differently than they do for WDM drivers. When you use the net start driver_name command to start the driver, the Windows NT 4.0-style driver typically asks for the resources, such as IO, Memory, IRQ, or other resources. When you run the net stop driver_name command, the Windows NT 4.0-style driver releases the acquired resources. The driver calls HAL routines, and these routines use the interface that the PCI bus driver provides.
