I have compiled my own cyanogenmod kernel for galaxy node 3, but i dont have much more knowledge about building from sources. If i can help, just say what i can do :)

I have another Problem. Most Videos will crash if i use mxplayer with HW acceleration. On Stock firmaware i can play them smoothly. Will post another logcat if i reflash again.
