This seems included in version 4.8-rc2:
$ git describe bafb2f7d4755bf1571bd5e9a03b97f3fc4fe69ae
v4.8-rc2-641-gbafb2f7d4755
I have kernel version 4.9.30:
$ uname -v
#1 SMP Debian 4.9.30-2+deb9u2 (2017-06-26)
but I still experience the bug. This is because, if I understand it right, the
commit containing this patch has been reverted in the production kernel:
################
commit 0ee72d8f9b8e17b8e4ccfebc7a25cbc2d395cd6a
Author: Greg Kroah-Hartman <<a href="mailto:gregkh@linuxfoundation.org">gregkh@linuxfoundation.org</a>>
Date: Wed Apr 12 15:49:39 2017 +0200
Revert "drm/i915/execlists: Reset RING registers upon resume"
This reverts commit f2a0409a08502d64fbe3990354dff5902b08d2fb which is
commit bafb2f7d4755bf1571bd5e9a03b97f3fc4fe69ae upstream.
It was reported to have problems.

I therefore wonder whether this means this bug is still there in the production
kernel.</pre>
