Is that the kodi.log after the reboot?
No, because the triggered reboot has not been finished - it crashed. The kodi.log has been taken right after a reboot crash. At that point, there was no SSH connection anymore, so I had to read the log files directly from MicroSD card.
Here is the kodi.old.log, taken at the same time like kodi.log (see above). If you compare both files, you will see additional errors at kodi.log (the crash log).
PS: Wir können uns auch deutsch unterhalten, falls es noch Unklarheiten gibt.
