Orange Pi 3 - irregular system freezing

I don't have an answer to that (yet).

In fact, I customized your adjustments (made for LE11) for LE10.

Never mind, now I've learned a bit about working with the diff utility.

I will do some experiments and we will see which change is significant.

I made two new versions:

V2 is without changing the CPU regulator voltage range and

V3, on the other hand, contains only a change in the CPU regulator voltage range.

First I tried V2. It ran for about half an hour and there was a system freeze.

Then I used the V3 version. So far, it runs smoothly for about 2 hours. This looks promising, but we'll see in two or three days.

Here is the contents of the V3 patch:

regulator-name = "vdd-cpu";
};

After a few days of daily use, I can confirm the previous conclusions.

There are no system freezes. Only occasionally Kodi crashes (LibreELEC lives during the crash - it responds to a ping) and this happens always and only during IPTV playback. First the image stops and after a few seconds Kodi restarts.

The significant factor is definitely the CPU regulator voltage range and not the wifi power supply.
