Симптомы:
пингуется
по ssh не соединяется (nmap говорит, что 22 порт открыт, но соединение отваливается по таймауту)
в web-интерфейс не заходит (nmap опять же говорит, что 80 порт открыт)
через UART тоже ничего не показывает
к контроллеру подключен wb-mr14, на нем желтая лампочка перестает мигать и просто горит
в логах пусто
Контроллер подключен через к сети проводом, питание по PoE.
Вырубаю/врубаю питание - все начинает работать (UART тоже) где-то неделю-другую, потом опять.
Собственно, стандартный вопрос - куда смотреть?
В вывод UART смотреть, можно какой-нибудь netconsole настроить в ядре.
Ещё можно wi-fi попробовать отключить, там был достаточно глючный драйвер от вендора.
Ну а вообще, стандартное решение таких проблем - это правильно настроенный под конкретное применение watchdog
странно, может и не связано, но стал с такой же периодичностью подвисать WB5. заметил, что после захода по SSH
Будем рады любым подробностям проблемы (кроме периода перезагрузок - это мы уже поняли

Да я сам рад найти какие-нибудь подробности, но даже в uart никакого вывода нет, когда зависло. Попробую подключить комп и круглосуточно сохранять все, что в uart вываливается.

Тут внезапно опять завис контроллер. В этот раз в UART выплюнуло вот такое:

Симптомы все те же, что описал вначале. Кстати, вопрос - почему watchdog не перезагружает контроллер в этом случае?

Такие же ошибки в логах были в этой теме Зависание WirenBoard5 каждые 2 часа
Выглядит как отказ sd-карты.
Потому что с точки зрения watchdog всё в порядке - описанные в его конфиге проверки система выполняет.
