This happens every time the GPU is under considerable stress, like decoding a va-api stream and running OpenGL apps at the same time. syslog records the hang: kernel: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung kernel: [drm] capturing error event; look for more information in /debug/dri/0/i915_error_state kernel: [drm:i915_wait_request] *ERROR* i915_wait_request returns -11 (awaiting 3263296 at 3263293, next 3263297) after 3-4 seconds the system resumes normal following the X crash a couple of minutes later: kernel: [drm:ironlake_update_pch_refclk] *ERROR* enabling SSC on PCH kernel: [drm:ironlake_update_pch_refclk] *ERROR* enabling SSC on PCH gpu related module opts are: i915.i915_enable_rc6=1 pcie_aspm=force i915.i915_enable_fbc=1 i915.lvds_downclock=1 at least rc6 enabled is mandatory for me since I ran a mobile gpu. any ideas? regards Dieter -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de
