Собственно с некоторых пор наблюдаю стабильное крошилово стима (даже если стим просто занимается скачиванием контента) и/или зависание X'овой сессии (если комбинировать первое с серфингом в хромиуме).
в dmesg присутствует нечто подобное
[ 1201.275596] [drm] stuck on render ring

[ 1201.276448] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.

[ 1201.276451] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[ 1201.276453] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

грешил на агрессивную настройку энергопотребления но после отката изменений не наблюдаю. собственно за ~30 минут с последнего ребута стим падал уже 3 раза как видно из лога.
собственно WTF?
