Может все таки вы глянете в каком именно месте может происходить сбой, а я уже сформулирую письмо в linux-netdev с описанием проблемы.

Вот тот же сеанс в видении ethereal. Разница начинается с 15-16 номеров строки. CGP не отсылает пакет "POP Continuation". Точнее он его возможно формирует, а ядро не отсылает.

Нормальная сессия:
