Я вижу некоторые странные ошибки в системном журнале. Я использую Debian 7.9. Кто-нибудь видел это раньше и / или знает, что может происходить? Мой жесткий диск выходит из строя? Я сделал fsck на днях при загрузке, и не было никаких сообщений, говорящих об этом. Это внешний зашифрованный жесткий диск USB (LUKS), который расшифровывается / монтируется при загрузке. На компьютере нет никаких RAID-массивов или чего-либо подобного. У меня есть два других диска, настроенных аналогично, без проблем.
Я посмотрел на смарт-данные для диска, и он говорит, что он прошел "общий тест на работоспособность". Есть ли что-нибудь еще, что я могу проверить / сделать, чтобы понять его состояние? Почему я получаю эти ошибки?

Я также посмотрел этот сайт, и один из авторов изменил свой файл sysctl.conf, как показано ниже, но мой уже настроен так ...
