Commit beaf5af48034c9e2ebb8b2b1fb12dc4d8aeba99e "drm/fence: add out-fences support" breaks backport of 92c715fca907686f5298220ece53423e38ba3aed "drm/atomic: Fix double free in drm_atomic_state_default_clear" Dunno if this double free can happen in 4.9, but the drm_mode_atomic_ioctl function does only create call drm_pending_vblank_event which sets event->base.fence || event->base.file_priv. So 92c715fca907686f5298220ece53423e38ba3aed makes sense. Attached my backport. Runs fine for a few days for me. Regards, Koos
