What ROM are you using? Do check the sources because there are different device trees used. If you are facing issues on the Note8 ROM, you can always stay at the v1 kernel but Safetynet wont work.just because you didn't experienced problems in your device, doesn't mean it won't have problems in other devices! in my j500m, when I install this kernel it keeps rebooting, and also some others users are reporting the same issue.
