Ошибка Ubuntu SDHCI

Question 1

Я использую ноутбук только с eMMC в качестве хранилища. Я использую Lubuntu 17.04

В течение некоторого времени мои /var/log/syslog и /var/log/kern.log были спамерованы с помощью:

В прошлом это было распространенной проблемой, но я не мог найти ничего полезного / недавнего.

Пожалуйста, дайте мне знать, если вам нужна дополнительная информация, чтобы предложить решение
