stop 0x9f driver power state failure windows 7

The nt!TRIAGE_9F_POWER structure provides additional bug check information that might help you determine the cause of this bug check. You can use dx (display debugger object model expression), a debugger command, to display this: dx KiBugCheckDriver. If a driver that is responsible for the error can be identified, its name is printed on the blue screen and stored in memory at the location (PUNICODE_STRING) KiBugCheckDriver. The verbose analysis displays the address of the nt!TRIAGE_9F_POWER structure, which is in Arg3.

In a kernel debugger, use the !analyze -v command to perform the initial bug check analysis.

To determine the specific cause and to create a code fix, programming experience and access to the source code of the faulting module is required.ĭebugging bug check 0x9F when Parameter 1 equals 0x3

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.
