From the report it is not clear to me if that is a regression you
experience from a previous kernel.

if so, and you have the latest working version and can reliably
trigger the problem, then it would be great if you can bisect the
problem (let me know if you need instructions).

First I would though suggest to as well test the most recent 7.1.5
kernel in unstable to verify if the problem persists.

Regards,
Salvatore
