Корневая файловая система случайным образом перемонтируется как readonly через несколько часов (Fresh install 11.10)

Сама корневая файловая система произвольно доступна только для чтения (обычно через 3-4 часа после перезагрузки) и должна быть перезапущена, чтобы снова работать. Я сделал новую установку после того, как проблема впервые появилась после обновления, но та же проблема все еще существует. Какая информация о системе вам нужна, чтобы помочь? Это 64-битная ОС, а корневая файловая система находится на SSD. Я запустил проверку fsck в файловой системе (даже после того, как переформатировал диск). Я также посмотрел на данные SMART, и это выглядит хорошо. Я обычно могу найти решение своих проблем с Google, но я не смог на этот раз. Спасибо за помощь.
