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: `[5280.261925] INFO: task mmcqd/0:37 blocked for more than 120 seconds.

Добрый день! Выглядит как (первый зафиксированный) случай отказа eMMC-накопителя. Мы в любом случае поменяем по гарантии, с вами свяжутся мои коллеги, чтобы организовать замену. Тем временем, покажите пожалуйста вывод команд ``` mount -t debugfs none /sys/kernel/debug/ cat /sys/kernel/debug/mmc0/mmc0\:0001/ext_csd | python -c 'import binascii, sys; print "~%d%% wear" % (ord(binascii.unhexlify(sys.stdin.read().strip())[0x5e])*10)' ``` ---
