Yes, our tunnels gained 2 bytes in 2.6.22. Maybe I would have seen the messages earlier with older kernels too, but our ADSL line started with 2.6.22. I tested a little bit around and found the ESP pmtud is doing it's job well. The message really just says what it does. Thank you for clarifying this and most notably for fixing the crash bug so fast!
