Is it happening with a single connection, or when trying tens, hundreds,
thousands? Is it stalled?
Could you send a packet capture for such connection? Thank you.

Please, try it with the most close configuration by using the
same config-file and running make oldconfig. There are some
issues fixed since that.

To be in position to assist you, the people of the list may wish more
details, like:
1. wireshark or tcpdump capture of the broken/stalled sessions;
2. iptables ruleset dump and running modules list;
3. more knowledge about your kernel configuration (config file);
4. more details about your HW, particular networking and their drivers
(is not it a HW/card/driver specific issue?)
Y may wish to look at how other people are submitting issues/bugs with
more details.
