Система зависает при копировании файлов с / на USB-накопитель, который использует любой формат

Я задам этот вопрос здесь, так как, похоже, я столкнулся с лидерами Linux Mint. Я использую Linux Mint в течение полутора лет. У меня 3 компьютера и 2 работают в Linux. Мой главный компьютер – настольная башня. Я переключил свой главный компьютер на UbuntuStudio пару дней назад, когда я разочаровался в Mint 18.2. Но проблема только немного уменьшилась и не исчезла с UbuntuStudio. И это серьезная проблема.

Симптомы состоят в том, что я не могу читать или записывать файлы с любого внешнего USB-накопителя без сбоя системы и полного замораживания. Привод может быть сформирован как NTFS, FAT32 или EXT4. Хуже всего это ext4. Единственный выход – жесткий перезапуск. (Выкл.) В эту проблему входят также карты памяти FAT32. Я могу передать несколько файлов, прежде чем система зависает. Но большие файлы или большое количество передаваемых файлов данных кажутся невозможными.

Эта проблема влияет только на один компьютер.

Компьютер:

  • Четырехъядерный процессор AMD FX ™ -4300.
  • Память: 16043 MiB.

Жесткие диски были отключены. Он имел 3 внутренних жестких диска для 5 ТБ пространства. Основной диск имел 1 ТБ пространства. Я заменил все эти диски одним 4 ТБ. Водить машину. Из-за этой проблемы накопители были отключены. (Я понял, что может быть проблема с одним из дисков.) У меня также около 25 ТБ хранения, которые я подключаю через USB-порты, включая RAID-башню. Все дополнительное хранилище отформатировано как NTFS. Но диски, которые были внутренними, считываются через внешний интерфейс жесткого диска. на этом компьютере нет встроенного устройства чтения карт памяти. Я использую адаптеры USB2 и USB 3 для карт памяти.

Смотря на журналы, я вижу, что PAM подписывает меня и часто. Меня подписывают как «root», так и «user». Когда я вижу, что передаваемые файлы начинают замедляться, и если я посмотрю журнал Auth, он покажет, что я только что был выписан пользователем.

Ниже приведены журналы Auth и System. Первый был скопирован и сохранен так же, как процесс копирования замедлялся. Спустя секунду компьютер замер. (Вторая копия / вставка ниже 2 из записей дня после повторного запуска.) Я попытался позволить ему сидеть в течение часа, чтобы узнать, может ли он восстановиться. Это не сработало.
