We used the QDMA driver on github, released for 2019.1 (That said, we also tried it with a few of our patches and found the same issues). 3. We operate teh QDMA in MM mode (well ST interfaces are also available, but we aren't using them). 4. We start a few queues. 4 queues seems to be enough to cause the bug to happen. 4.
