This warning does not occur on the Ubuntu 4.8 kernel. It might be fixed by upstream Linux 4.5 commit d88270eef4b56bd7973841dd1fed387ccfa83709 "tcp: fix tcp_mark_head_lost to check skb len before fragmenting". https://github.com/torvalds/linux/commit/d88270eef4b56bd7973841dd1fed387ccfa83709 **

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.12
