<pre>And not using stolen for the ring buffer also cures it:
@@ -2049,7 +2049,7 @@ static int intel_alloc_ringbuffer_obj(struct drm_device
*dev,
struct drm_i915_gem_object *obj;
obj = NULL;
- if (!HAS_LLC(dev))
+ if (!HAS_LLC(dev) && !i915.enable_execlists)
obj = i915_gem_object_create_stolen(dev, ringbuf->size);
if (obj == NULL)
obj = i915_gem_object_create(dev, ringbuf->size);
I would assume our ring should be empty when we resume, so it shouldn't matter
that stolen gets clobbered. But this patch says otherwise.</pre>
