Kodi 15 ... this thread here, that you highjacked, is about VideoPlayer enhancements which are not in OpenELEC 6.0.x ... as your GPU hangs and your dmesg clearly shows that - you don't have much chances. It's a kernel / mesa / drm bug and DVDPlayer (the internal player at this ancient time) provokes that bug.
So: Use latest Milhouse build that you can find and see if the issue is gone.
