hi, I also have the similar entries in my dmesg, though my problem is a little different from yours and my bisect lead to another commit. And that also is still not fixed (last tested with 4.0).
Thank you for the pointer, but this seems to be an unrelated issue. I tried applying the patch, but it doesn't fix the issues that I'm experiencing.
