Hi All,
I have written the WDF driver with pnp callbacks EvtDeviceSelfManagedIoInit amd EvtDeviceSelfManagedIoCleanup.
In EvtDeviceSelfManagedIoInit i am creating the systemthread using PsCreateSystemThread which wait for workitem semaphore (KeWaitForSingleObject).
My EvtIoDeviceControl puts request into workitem list_entry and set above workitem semaphore.
System thread process this request and again wait for workitem semaphore.
To exit above thread my EvtDeviceSelfManagedIoCleanup sets workitem semaphore without putting workitem in list_entry so that system thread can exit by checking empty list_entry.
When i install my driver thread is starting and IOCTL processing is happening.
But when i sleep and resume i got DRIVER_POWER_STATE_FAILURE BSOD every time.
Below is dump analyze:
DRIVER_POWER_STATE_FAILURE (9f)
A driver has failed to complete a power IRP within a specific time.
Arguments:
Arg1: 0000000000000003, A device object has been blocking an Irp for too long a time
Arg2: ffffe00001a74060, Physical Device Object of the stack
Arg3: fffff802c2fea840, nt!TRIAGE_9F_POWER on Win7 and higher, otherwise the Functional Device Object of the stack
Arg4: ffffcf8002786d80, The blocked IRP

NOTE: With only driver verifier running i got above BSOD.
I am not understanding what is blocking irp here.
Please let me know if anyone has information on above BSOD.
