Can enable the legacy turbo back and see if it helps? diff --git a/drivers/gpu/drm/i915/i915_irq.c b/drivers/gpu/drm/i915/i915_irq.c index 9baecb7..0dac413 100644 --- a/drivers/gpu/drm/i915/i915_irq.c +++ b/drivers/gpu/drm/i915/i915_irq.c @@ -4292,12 +4292,7 @@ void intel_irq_init(struct drm_i915_private *dev_priv) INIT_WORK(&dev_priv->rps.work, gen6_pm_rps_work); INIT_WORK(&dev_priv->l3_parity.error_work, ivybridge_parity_work); - /* Let's track the enabled rps events */ - if (IS_VALLEYVIEW(dev_priv) && !IS_CHERRYVIEW(dev_priv)) - /* WaGsvRC0ResidencyMethod:vlv */ - dev_priv->pm_rps_events = GEN6_PM_RP_UP_EI_EXPIRED; - else - dev_priv->pm_rps_events = GEN6_PM_RPS_EVENTS; + dev_priv->pm_rps_events = GEN6_PM_RPS_EVENTS; INIT_DELAYED_WORK(&dev_priv->gpu_error.hangcheck_work, i915_hangcheck_elapsed); based on the comments looks like we are hitting the issue after enabling aggressive downclocking. I will check the patch again to see if we can potential fix. 8fb55197e64d5988ec57b54e973daeea72c3f2ff drm/i915: Agressive downclocking on Baytrail Thanks Deepak</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>
