Note, the .config is randconfig derived. There was a stage of the tests when about every ~5-10th randconfig was failing, so i dont think it's a rare config combo that triggers this. (but there were other stages where 30 randconfig in a row went fine so it's hard to tell.)
In the worst case the hang needed 2 million packets to trigger - that's why i set the limit in the tests to 6 million packets.
