Can you try with the latest version in the 6.1.x series to see if the problem 
is still there?

If the problem is still present in the latest 6.1 kernel, then you need to find 
out which patch(es) actually fix the problem.
The easiest way to start with that is to find the last kernel which exhibits 
the issue and then the first one where it is fixed.
https://snapshot.debian.org/binary/linux-image-amd64/ should help with that.

When the range has been narrowed, a `git bisect` should identify the specific 
commit(s) which fixes the issue.
https://wiki.debian.org/DebianKernel/GitBisect should help with that

When that/those have been identified, it should be reported to the upstream 
kernel so that they can incorporate those fixes in their LTS kernel(s) which 
Debian then will pick up automatically.
