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 the
introduction 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.
