The problem is mentioned here too http://lkml.org/lkml/2009/9/24/444 but there hasn't been any response.
I was unaware of this, as there is no bug report assigned to me about it. Does this also happen with 220.127.116.11?
there's a bit of discussion here... but, afaik, the patch linked after several back-and-forths didn't actually solve the problem for sure. http://lkml.org/lkml/2009/9/24/167
