Additional Kernel errors

emonSD

Since swopping out my SD card this afternoon I’m now seeing these errors repeated endlessly through several log files. This was the preinstalled card from the online shop.

I also carried out a Full Update through the Admin Page.

Yes, I’d noticed these but not done anything more about them.

Quick Google, looks like 1-wire has been enabled.

I’m happy that it’s known about then.

That’s the problem with log files, the temptation is always there to check them :slightly_smiling_face:

Well sort of!

If you are interested, you could try the fix from one of the links. Also there is a risk the logs are not rotating correctly.

I suggested a revised logrotate scheme here Changes to logrotate package are causing issues · Issue #155 · openenergymonitor/EmonScripts · GitHub although Trystan has not picked that up yet.

I disabled 1-wire through raspi-config as one of those links suggested that has removed those errors. I’ll need to keep a note that I’ve made a change from the supplied install.

Cheers

1-wire is used for temperature sensing, it was intentionally enabled on the new image. It looks like these messages are harmless?

It would be good to clear these if we can, thanks for creating the issue @borpin

Directly to the Pi? I thought the add-on board did the sensing? There should be a mechanism for enabling/disabling this.
