--- Comment #11 from David Weinehall <david.weinehall at intel.com> ---
Can you test if you can reproduce the bug with:

* enable_execlists=0 + only S3
* enable_execlists=0 + only S4

In my testing I can only reproduce the issue when s4 is involved; when
execlists are disabled S3 will not trigger any bugs (if execlists are used I
can trivially trigger a similar -- not necessarily identical -- issue by using
just S3).
