ArchLinux - система зависает и перестает отвечать на запросы

У меня были проблемы с конкретным ноутбуком в течение нескольких недель. Другой с той же ОС и обновлениями работает нормально (так что я думаю, что это аппаратная проблема). Похоже, что система зависает, когда я выполняю много операций ввода-вывода (например, копирую файл или выполняю любую нагрузку на процессор). Кажется, он не вернется к жизни, пока я не перезагружу компьютер. Первоначально я думал, что это проблема Firefox или Chromium, а затем FlashPlayer. После того, как я убил Firefox или Chromium, мой компьютер снова стал реагировать, но в конце концов снова перестал отвечать.

Я вижу это в dmesg:

Похоже, что у меня плохая память - также мой жесткий диск показывает, что он находится в предустановленном состоянии. Я не знаю, будет ли это способствовать или нет (я сомневаюсь, так как все эти программы уже должны быть в памяти).

Я запустил тест памяти memtest86, и он не нашел ошибок. У меня плохая память или что еще здесь происходит? Я хочу знать, что сломано в моей системе и есть ли у вас какие-либо идеи о том, как это исправить.
