Just to let you know you're not alone ... but I can't make any sense of
this either. The bfdq is the elevator_data, which is initialised when
the scheduler is attached, so it shouldn't change. Is it possible to
set a data break point on elevator_data after it's initialised and see
if it got changed by something?
