Rooting and keeping with the stock kernel

It's month now when SGS6E+ is out in the wild and we don't have many devs in the comunity so far... I greately appreciate the only custom kernel we have, but what about just rooting, and keeping stock at the same time? Pure stock and root.
I still can't find any solution for such a basic need: a stock rooted kernel. You can say: hey there is one:
http://forum.xda-developers.com/s6-edge-plus/development/auto-rooting-stock-kernels-s6-edge-plus-t3194607/

..but when I went thru the comments... so many issues... Why?

Truely speaking, i tried to compile my own kernel, but... I'm a noob and only achieved to set up the environment: ubuntu... all the needed packages... but then I noticed there were no newest sources for G928F on samsung site....G928FXXU1AOH4. Even if they were available, I would rather fail building it :)

Any ideas?

Something Keeping Phone Awake Causing Battery Drain

Hey everyone, I have the Verizon variant of the LG G4. I am rooted and running Xposed and some other apps. I have amplify installed as well and BBB. I have the phone mostly debloated as well. I am getting some really weird stats in BBB however which seems like it is causing massive battery drain. See attached pics of screenshots I took within BBB. Does anyone have any idea what is keeping my phone awake for over 10 hours and draining the battery so poorly? Thanks in advance!
