[Comm] "замерзания экрана" на ноуте с видяхой intel

[Maks Re]

Здравствуйте,

имею ноут lenovo x220
video - intel

дистрибутив - SL7, ядро последнее, 3.10.18-std-def-alt1

обратил внимание, что стало часто замирать экран (никаких действий,
ничего не нажимается и пр.)

потом отмирает... можно продолжать.

в логах вот:
