The problem is in IoSecondStageCompletion. Sometimes Irp->UserEvent points to Fileobject->Event. Dereferencing such an event object crashs ros.
Actually, according to the stack traces people are giving me, it's dereferencing the File object that's causing this...
This isn't right. I've add a second test condition (Irp->UserEvent != &FileObject->Even) on both points where the event is dreferenced. This does fix the crash.
