I am getting this when I enable Driver verifier on my driver

DRIVER_VERIFIER_IOMANAGER_VIOLATION (c9)
The IO manager has caught a misbehaving driver.
Arguments:
Arg1: 0000000000000220, IRP_MJ_SYSTEM_CONTROL has been completed by someone
other than the ProviderId.
This IRP should either have been completed earlier or should have been passed
down.
Arg2: fffff880041a29f0, The address in the driver's code where the error was
detected.
Arg3: fffff980022fed30, IRP address.
Arg4: fffffa800415f060, ProviderId.

Here is the part of the code its pointing at
NTSTATUS MySystemControl( IN PDEVICE_OBJECT fdo, IN PIRP Irp)
{
NTSTATUS status;
PDEVMSTR_DEVICE dx = (PDEVMSTR_DEVICE)fdo->DeviceExtension;

if( dx->IODisabled)
{
Irp->IoStatus.Status = STATUS_DEVICE_NOT_CONNECTED;
Irp->IoStatus.Information = 0;
IoCompleteRequest(Irp,IO_NO_INCREMENT);
return STATUS_DEVICE_NOT_CONNECTED;
}

// Just pass to lower driver
IoSkipCurrentIrpStackLocation(Irp);
status = IoCallDriver( dx->NextLowerDriver, Irp);

return status;
}

Any help would be appreciated.

You should pass the IRP down. That's what the bugcheck explanation tells
you.

Expanding on Alexender's answer, IRP_MJ_SYSTEM_CONTROL is used to implement
WMI, and WMI needs to operate whether or not your device is enabled. You
have to pass them all along.

I tried that.

Then the verifier started complaining about something else. I will post the
details when I get a chance.
