** Description changed: I'm having regular system freezes with Ubuntu 12.10 and a Core i3-3240. + No VT switch or magic keys does anything, the only option is a hard reboot. Syslog prints many stack traces and: kernel: [ 589.450890] [drm:__gen6_gt_wait_for_thread_c0] *ERROR* GT thread status wait timed out I've disabled RC6 with i915.i915_enable_rc6=0 kernel parameter, the the freezes seem to be gone so far.
