После обновления не загружается контроллер WB5.8

Добрый день.
Решил сделать обновление контроллера WB5.8 Причина долго не обновлялся и появились проблемы с модулями WBIO-DI-DR-16. Выполнил apt-get update && apt-get upgrade -y. В ходе обновления было предложено перезаписать fstab. Ответил нет. Контроллер немного подумал и сказал что необходимо выполнить dpkg --configure -a. Выполнил и повторил обновление. В итоге контроллер отписал что обновлено 0 пакетов удалено 0 пакетов ничего не сделано 12 пакетов. Перезагрузил контроллер, убедился что он загрузился и пошел спать. Но оказалось что он через минуту ушел в перезагрузку и так всю ночь. Подключился через отладочную консоль. Вывод следующий:

После этого выкидывает из отладочной консоли. Подскажите, пожалуйста, мои дальнейшие действия. При крайнем обновлении были проблемы с sources.list, но вроде обновился

Добрый день.
Для начала - советую остановить watchdog
аппаратным способом - излишне, достаточно после запуска контроллера остановить сервис.

А какая версия ОС на контроллере?

Пока остановить watchdog программно не получилось. Вот окончательный вывод из консоли

Версия ос 7.11

Подскажите, мои дальнейшие действия? В консоль вошёл, watchdog отключил. Возможно ли восстановить без перепрошивки? Куда двигаться дальше? Почему постоянно сыпеятся сообщения connection refused?

7 - давно не поддерживается. советую обновить:
