I can't see any problem in the files attached so far. We need a log file covering the period of time when the problem actually happened. To get that please:

1. Reproduce the problem.

2. Reboot and then immediately run:

   journalctl -b-1 > prevboot.txt

   and then attach the file 'prevboot.txt' to this bug.
