Hi,
I think it is rather an issue which I should opened with the kernel maintainers, I have noticed that after switching from 6.0.15-1 to 6.1.1-1 kernel suspend stopped working. I can see in logs the following entries:

Looks like the issue with the sound driver, there was a lot of changes to cs35l41-hda in 6.1 Changelog or it might be something else?
Does anyone have any suggestions before I do that?
Thanks a lot!
