I couldn't reproduce the issue on any of the upstream versions. I have
tried v4.9, v4.8 and even on latest v5.11. No issues there. There is no
upstream version 4.9.258.
Jim mentioned Debian 10 which is based of kernel version 4.19 is also
fine. Issue appears to be only affecting Debian 9(kernel v4.9.0-14).
