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  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  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.
