<pre>I also see this on shard-glkb with drm-intel-fixes.
Particularly it got worst with latest round with fixes on top of 4.14-rc6:
dc35b1129cc3 drm/i915: Hold rcu_read_lock when iterating over the radixtree
(vma idr)
23e873389d84 drm/i915: Hold rcu_read_lock when iterating over the radixtree
(objects)
7c838e2a9be5 drm/i915/edp: read edp display control registers unconditionally
8777b927b92c drm/i915: Do not rely on wm preservation for ILK watermarks
713946d16f45 drm/i915: Cancel the modeset retry work during modeset cleanup</pre>
