A friend of mine told me that his OPi One freezes every couple of days for no reason. So I took it with me and see what I could find.

I connected another SBC via serial to the board and wait until it freezes. This is what I have got and no idea what the reason is....

The armbianmonitor output is from a fresh restart after power cycle.

Want Armbian t-shirt or a cup?

Can you compare the dts of this kernel with earlier kernel? (v20.02 -- arch/arm/boot/dts especially cpu entries)

Seems like upstream did refactoring, I didn't want to touch anything since I've no way of testing changes.

I had these freezes also with my OPi One - no matter with armbian current or dev (buster & focal).

I hadnt this in 2019.

I did see it, because I used him as one of my piholes and when he did freeze some of my android-devices did act not normally while using the web (they seem to have a problem with using the 2nd dns in the network-settings)

I have another One running for month now (also as Pihole) and never had issues with it.

Issue recreated, though other virtual address this time.

That is not related to this specific issue. Armbian cannot clock higher on H3 since there is no proper support for the voltage regulator.

But I think its only a software problem.....this One reacts like he has a bad armbian-image ;)

In theory you were right, but unfortunately it is not. I have two OPi One side by side. One with the defect and one known to work. I swapped the sd cards and the sd card out of the defective board booted flawless on the known-to-work board while the known-to-work sd card did not boot in the defective board.

 

After a dozen power cycles it came back once but I do not trust it anymore.

Have you tried powering through GPIO pins?
