Please, try it with the most close configuration by using the same config-file and running make oldconfig.

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. -- Sincerely, Robert Iakobashvili, coroberti %x40 gmail %x2e com ........................................................... http://curl-loader.sourceforge.net A web testing and traffic generation tool.
