Can you rule out that you don't have a power problem?

I finally managed to look at the PS. I digged out my old analog 100MHz Hameg scope and attached it to the 5V pin of the GPIO connector.

• The power supply is a 2.5A type
• I can see a stable Voltage of about 5.5V

5.5V? A bit too high for my understanding. Original Pi PSU has 5.1V output

There's a periodic ripple of around 50mV, likely the remaining voltage ripple from the switching power supply (it has the typical fast rise slope and afterwards a slow descending region)

There's some additional noise on the line of around 100mV, supposedly side effects of the CPU, GPU, etc. using different amounts of current.

Unfortunately the RapsberryPi foundation gives no detailed information about the PS, just 5V and some vague current rating:
Raspberry power supply
No data about admissible accuracy, ripple, noise, etc. But I think 50-100mV should be OK.

Yes, should be. But if there are any short spikes, I don't believe that you can see them with your old Hameg analogue scope

Will need to reinstall again

Maybe you have same issue reported in this thread

Please check /etc/fstab. If /boot ist not mounted correctly, Kodi will not come up
