        ok, then can you try the attached patch, it solves dst cache
problem for another user, may be it will help you too. This patch can
be used with or without routes patches. It makes sure we don't leak
dst entry in bridge-netfilter. If the patch does not help let me know
and we can add some printks to catch the problem.
