An isochronous data transfer through an IEEE 1394 device suddenly stops in Windows Vista or Windows Server 2008

On a computer that is running Windows Vista or Windows Server 2008, when you perform an isochronous data transfer to or from an IEEE 1394 device, the isochronous data transfer suddenly stops.

In this scenario, if you have enabled the Driver Verifier for the driver that the device uses to perform the isochronous data transfer, the operating system crashes. Additionally, you receive the following Stop error message on a blue screen:

STOP 0x000000D1 (parameter1, 00000002, 00000001, parameter4)
DRIVER_IRQL_NOT_LESS_OR_EQUAL ohci1394.sys
