I've tried the following patch diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index d7f237d..7769768 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -6527,7 +6527,6 @@ void ironlake_enable_rc6(struct drm_device *dev) ADVANCE_LP_RING(); I915_WRITE(PWRCTXA, dev_priv->pwrctx->gtt_offset | PWRCTX_EN); - I915_WRITE(RSTDBYCTL, I915_READ(RSTDBYCTL) & ~RCX_SW_EXIT); } /* Set up chip specific display functions */ And it still hangs.
