I get this peculiar error from WHQL tests on a kernel mode driver.
The driver creates a PDO for user mode programs to communicate with it. The code to create this PDO follows that in kbfiltr from the sample code save creating a SpinLock & a ring buffer.
The driver is a mouse class driver, PnP driver. (Mouse drivers are typically not necessary, but we need it as there are some bugs in the HID reports sent by the device firmware that need to be addressed).
Research on the Net did not yield anything specific regarding this message.
Anyone else encountered this error? What could be the root cause?
