T440s, случайным образом замораживающийся на [закрытой] Ubuntu 14.04 и 15.04

Мой T440s thinkpad случайным образом замораживается при выполнении и LTS и текущего релиза Ubuntu. Я не имею смочь определить шаблон к замораживаниям.

Это произошло на Монетном дворе 17.1, таким образом, я попробовал новые установки Ubuntu 15.04 и Ubuntu 14.04, и это происходит на обоих.

У меня есть Intel Graphics.

Никакие ярлыки Escape, кажется, не работают, я попробовал всех их включая ctrl-alt-backspace и alt-printscrn-R/E/I/S/U/B

Вот мои прошлые 10 минут записей системного журнала, прежде чем это замерзнет, если бы кто-либо может предложить предложения, я был бы очень счастлив!
