Sorry, the dev still needs more info. This is what he wrote to me:
QuotePlease ask for the kodi.old.log immediately after the RPi has rebooted (with debug enabled, run pastebinit .kodi/temp/kodi.old.log immediately after reboot).
The last two crashlogs were empty and the one from the first post seems like some unrelated crash from a normal shutdown.
It doesn't look like some crash, more like an intentional reboot or shutdown+poweron - maybe from the gpio-shutdown overlay / button cabling
- enable permanent log level 1 by creating an advancedsettings.xml file
- reboot
- replicate the issue
- run the above command, and post the resulting URL
