Did this issue start happening after an update/upgrade? Was there a
kernel version where you were not having this particular problem? This
will help determine if the problem you are seeing is the result of a
regression, and when this regression was introduced.   If this is a
regression, we can perform a kernel bisect to identify the commit that
introduced the problem.
