Мы обновили один из наших центральных маршрутизаторов, который ужасно устарел, с помощью apt-get dist-upgrade
с Debian Squeeze с Wheezy до Jessie.
Но теперь мы видим следующие ошибки в dmesg

Это происходит для всех интерфейсов с волоконно-оптическим интерфейсом 1 Гбит примерно каждые 2 секунды.
Некоторые пользователи даже сообщали о нестабильном соединении.
Что это значит? Это из-за устаревшего оборудования?
Мы планируем купить новый, но как мы можем решить эту проблему, пока новый маршрутизатор не будет доступен?
