Yeah, this is due to changes backported from kernel 6.5, which Ubuntu decided to include in 6.2 while many other distros skipped 6.2 completely.

I have PR which I'll push the fix into. (#1119)

Thank you very much (edited your changes in PR and i am up and running)

I've just now updated the PR with a more proper fix taking into account kernels 6.3, 6.4 and Ubuntu 23.04 with kernel 6.2.
