If you think this is a kernel issue please confirm this using a different older version or -lts kernel or some other branch. Then also check/report this upstream.

Thanks, I've switched to the LTS kernel. Will keep an eye out.

Are there any debugging options I can enable to get more logs?

Is this still an issue?

It has happened but just once since switching to the LTS kernel (in July). I am not sure if it's fully solved or not but good enough for me at least. Happy to help investigate if you think we should.
