Likely to be another side effect of commit c501ae7f332cdaf42e31af30b72b4b66cbbb1604 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Wed Dec 14 13:57:23 2011 +0100 drm/i915: Only clear the GPU domains upon a successful finish By clearing the GPU read domains before waiting upon the buffer, we run the risk of the wait being interrupted and the domains prematurely cleared. The next time we attempt to wait upon the buffer (after userspace handles the signal), we believe that the buffer is idle and so skip the wait. There are a number of bugs across all generations which show signs of an overly haste reuse of active buffers.
