After some suspend/resume cycles on my Samsung N210 netbook with Atom N450 CPU, graphics become very slow/unusable, and my dmesg is full om errors like this: [43373.908075] [drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... render ring idle [waiting on 222265, at 222266], missed IRQ?
