Yes, I confirmed IoCompleteRequest is not the culprit. I had the opportunity
to complete that Irp in the lower driver before the upper driver call
IoGetDmaAdapter …which causes IRP_MN_QUERY_INTERFACE …which is causing
all these problems : )
But how is it possible that if from my lower driver (which is above a
windows provided pci bus driver) I use IoGetNextIrpStackLocation() or I use
IoCopyCurrentIrpStackLocationToNext() they are successful.
And Irp->CurrentStackLocation is correct (=2) and DeviceObject->StackSize is
2 and Irp->StackCount is 3 (both seems correct) and yet I am getting
IRP_NO_MORE_STACK_LOCATIONS !
