This still doesn’t explain why it works with older kernels, but not newer ones.
Can you try the different 3.12-rc kernels? The information that this was
introduced in 3.12-rc1 as opposed to a specific -rc>1 releases may help
the guys here to pinpoint what exactly caused the behavior change on the
receiver side.
I can reproduce the problem with 3.12.0-rc1 as well.
I also tried 3.11.10 again, to make sure it did not have the problem even when forcing requests to a non-SACK-enabled loadbalancer, and it works as it should (no hung connections).
