Slightly high cpu load in the latest version of nerves_system_rpi4

I created two firmwares for raspberry PI 4, one with version 1.28.1 and the other with the latest version 1.29.0.

From the latest version I get this cpu load when the pi is doing nothing

The load is between 0.5-0.9 all the time

while from the first firmware (old version), it’s always the nice zeros

Is it something to worry about or it’s fine as it is ?

This is strange, but I just looked and I’m seeing non-zero numbers too.

Looking at the Changelog, there are things to blame, but I’d want to verify first.

Thanks for bringing this up. Would you mind posting a short issue to track it?

Yes, I’ll create an issue in github.
