Thank you, what do you mean by ‘hostap-WIFI’.
Here is a picture (snippet) of the screen, but I can try to take a better picture with the next restart, but the screen changes very quickly from this point on.
Yes, I had the addon ‘cpufrequtils’ installed, but just to see if the system graph (CPU frequency) is displayed correctly. Could it be that the boot messages are related to the add-on, if so, it should have disappeared after the restart?
