The sequence of events leading to the warning is as follows: ironlake_irq_handler() ilk_display_irq_handler() cpt_irq_handler() intel_hpd_irq_handler() i915_hotplug_work_func() intel_dp_hot_plug() intel_dp_check_link_status() intel_dp_get_link_status() intel_dp_link_down() drm_helper_hpd_irq_event() drm_kms_helper_hotplug_event() drm_sysfs_hotplug_event() kobject_uevent_env() <userspace uevent processing> drm_mode_obj_set_property_ioctl() drm_mode_connector_set_obj_prop() intel_connector_dpms() intel_encoder_dpms() intel_crtc_update_dpms() ironlake_crtc_disable() intel_disable_dp() intel_dp_link_down() There were several changes on these paths, but I fail to find there a change that would prevent from intel_dp_link_down() to be called twice on SNB or IVB.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
