There appears to be 2 different traces that repeat whenever the screen goes through that turn off-turn on cycle (but at first, only the first trace is shown). I believe the screen turns itself off at the time this message is printed: "Aug 26 07:25:04 nc052 kernel: [drm:i915_runtime_suspend] Suspending device" First trace: Aug 26 07:25:04 nc052 kernel: [drm:i915_runtime_suspend] Suspending device Aug 26 07:25:04 nc052 kernel: [drm:hsw_enable_pc8] Enabling package C8+ Aug 26 07:25:04 nc052 kernel: ------------[ cut here ]------------ Aug 26 07:25:04 nc052 kernel: WARNING: CPU: 0 PID: 60 at drivers/gpu/drm/i915/intel_display.c:6888 hsw_enable_pc8+0xae/0x6f0() Aug 26 07:25:04 nc052 kernel: CRTC for pipe A enabled Aug 26 07:25:04 nc052 kernel: Modules linked in: Aug 26 07:25:04 nc052 kernel: CPU: 0 PID: 60 Comm: kworker/0:1 Not tainted 3.15.4-ARCH-00041-gf4db98240ac2 #21 Aug 26 07:25:04 nc052 kernel: Hardware name: Apple Inc.
