And this report doesn't happen with the older patch? (Did you do the
same testing with the older patch that triggered this)
Because this looks like a *different* incarnation of the same
lock->lock->delayed work/timer that we're trying to fix here -- the
delayed work is now rmpp_recv->cleanup_work in this case instead of
mad_agent_priv->timed_work as it was before.
