Completed IRP but did not call PoStartNextPowerIrp.

Device object freed w/ outstanding uncompleted power request.

The device object completed the IRP for the system power state request, but it did not call PoStartNextPowerIrp.įor a description of the possible causes, see the description of each code in the Parameters section. The target device's device object, if available The device did not complete its Directed Power Transition callback successfully. Indicates if this was a Directed Power Down(1) or Power Up(0) completion. The device failed to complete a directed power transition within the required amount of time. The power state transition timed out waiting to synchronize with the PnP subsystem. The thread currently holding onto the Plug-and-Play (PnP) lock. The physical device object (PDO) of the stackĪ device object has been blocking an IRP for too long a time. The device object completed the I/O request packet (IRP) for the system power state request, but it did not call PoStartNextPowerIrp. The target device's device object, if it is available The device object that is being freed still has an outstanding power request that it has not completed. Parameter 1 indicates the type of violation. If you are a customer who has received a blue screen error code while using your computer, see Troubleshoot blue screen errors.
