However, I think you probably need to run a "git bisect" to point out the offending commit. And it looks like you already have some good starting point to use for the git bisect. I have also looped in some of the developers from Realtek/Realsil, please keep them in the loop, as they know this HW and driver. Kind regards Uffe
