Добрый день.
После заказа WB5 (rev 5.6), установки, подключения и настройки он работал без нареканий где-то полгода. Однако буквально на днях повис. На пинги отзывался, но ни по WebUI ни по SSH не отвечал. Debug UART на команды не отзывался. После передергивания питания завелся и работал как ни в чем не бывало еще часа 4, потом точно так же завис. Обновил на последнюю стабильную прошивку, обновил систему через apt-get upgrade - не помогло. Передернул питание еще раз, выгрузил все сервисы из памяти и модули ядра, запустил memtester на ночь. Наутро WB оказался также зависшим, в консоли были логи 36 полных успешных тестов мемтестера.
Подключил Debug UART и включил WB, запустив в консоли tail -f /var/log/messages. проработав 1,5 часа WB повис, в консоль выдал следующее:
