Я заметил ниже отслеживания стека, обнаруживается в /var/log/kern.log. Под управлением Ubuntu 14.04 на 3.13.0-32-универсальном ядре. Этой проблемы часто не происходит.

Это, известная ошибка планирования, которую я поражаю? Действительно ли там какие-либо патчи доступны?

Эта проблема замечена при загрузке пользовательского рычага netfilter (.ko) на моем поле, когда высоко загружают входящие сетевые пакеты, проблема не восстанавливаема каждый раз.
