I was able to reproduce it last night with 2.6.32 on Centos 6.3 so it does not seem confined to just the 3.X tree. I think this is something that's been lurking in the kernel for years and just has a hard time showing up. Bugs that go away on their own come back on their own.
I got a trace of the traffic but need one of the os. I'll attempt to get a trace of this again since I seem to be able to reproduce it by routing NetFlix traffic through the router while I am streaming live videos on Linux. I will setup the system to trap the bug and post the traces.
