Maybe I should clarify a little bit. I meant that that message is missing
before the problem happens. The interface message appears after the problem
was detected.

And maybe I should also inform you that many batman-adv refcounting
patches [1] for some long standing problems are getting queued up by the brave
linux-stable people. But there are also two patches [2,3] which Antonio hasn't
submitted yet.

Kind regards,
