Chris Wilson cd977c84fc drm/i915: Reset last_retired_head when resetting ring ... commit c3b2003792 upstream. When we reset the ring control registers, including the HEAD and TAIL of the ring, we also need to reset associated state. In this instance, we were failing to reset the cached value of ring->last_retired_head and so upon the first request for more space following a resume would potentially (depending on a narrow race window) believe that the HEAD had advanced much further than reality.
