There is no clear indication here of any error that would result in a Kodi crash. The last time any CEC reference was in the log was 81 seconds prior to the crash end of the log. While yes, CEC may have had some issue, it hardly seems to be the reason for the crash. You said yourself that disabling CEC still results in crash/freeze.
