Hello Alexander, it seems that the log is keeping all the information that you
already shared in the first attachment. Could you reproduce with a clean
kern.log, since it shuts I guess a dmesg can't be obtained.
To clean kern.log:
# rm /var/logs/kern.log
# reboot
The kern.log will regenerate after boot.</pre>
