This looks different. Here there isn't the evidence of confusion in the
ringbuffer, but that the CS kept reading past the batchbuffer - indicative that
the batchbuffer is incoherent.
Did this issue start occurring recently? Perhaps a change in 3.17.y? If so, is
there any chance you could bisect it?</pre>
