Is there any limitation to opening a driver's own device via IoGetDeviceObjectPointer? I create a device in DriverEntry (DO_DEVICE_INITIALIZING is unset before IoGetDeviceObjectPointer is called), and try to open it from a system thread (while DriverEntry is still in progress, but the device is set up already, DriverEntry waits for the system thread to exit), but am getting STATUS_NO_SUCH_DEVICE (not STATUS_OBJECT_NAME_NOT_FOUND like when the device doesn't exist at all).
Any idea what could be up?
