Calling WdfIoQueueRetrieveNextRequest from ISR DPC

After you called WdfInterruptAcquireLock, you’ve raised to DIRQL.

( really, man… we all are on a schedule and no time for ramp-ups, but
sometimes have to take the time )

Hello,

I’m calling WdfIoQueueRetrieveNextRequest from ISR DPC.
This causes blue dump with the following details in the event log:

Error code 1000008e, parameter1 80000003, parameter2 804e3b14,
parameter3 80550790, parameter4 00000000.

According to the documentation it is possible to call
WdfIoQueueRetrieveNextRequest at dispatch level.

What am I doing wrong ?

Thanks.
VOID PLxEvtInterruptDpc(
IN WDFINTERRUPT Interrupt,
IN WDFDEVICE Device
)

NTSTATUS status;
PDEVICE_EXTENSION devExt;
WDFREQUEST request;

WdfInterruptAcquireLock( Interrupt );

status = WdfIoQueueRetrieveNextRequest(
devExt->IoControlQueue,
&request
);

WdfInterruptReleaseLock( Interrupt );
}

I would suggest you hook up a kernel debugger and run !analyze -v when the bugcheck occurs (and make sure you have the correct symbols). Send the output of this command to the list to have any hope of help debugging this
