I built the next test kernel, up to the following commit: b768b16de58d5e0b1d7c3f936825b25327ced20c
The test kernel can be downloaded from: http://kernel.ubuntu.com/~jsalisbury/lp1686636/b768b16de58d5e0b1d7c3f936825b25327ced20c Can you test that kernel and report back if it has the bug or not? I will build the next test kernel based on your test results.

Symptom: Outgoing connections (ssh, tcp to port 80, to port 8080) fail to establish about 25% of my attempts. I then switched the kernel from linux-image-4.10.0-20-generic (zesty) back to linux-image-4.8.0-49-generic (yakkety) and those problems were gone. I have no iptables rules on my system. I'm using an e1000e over gigabit wired network. Attached is a tcpdump of a connection attempt.
