Hi Doron,
I got the problem my driver has a Interrupt resource exposed from BIOS and
the interrupt is forwarded by its master device (GPIO interrupt controller
driver) so if i register the GPIO resource in its _AE1 handler and also
expose that resource in my driver my driver is unloading.
But my question is if that interrupt resource is a problem why its not
giving problem in PrepareHardware.
I want to know what is going underneath how can i find that problem from
windbg.
Regards,
Rabish
