Hi,
i'm experiencing the exact same problem on a freshly flashed SD card with neuron-node-red_image-20220406.0.zip
@knebb your tip fixes this, so thanks for that.
i guess it probably needs a more structural fix, so hopefully this will be included in the next available flash image...
thanks anyway for posting this... it fortunately solves my problems without a lot of haystacking
Cheers, Tony
Hi @Martin-Kudláček ,
Sorry to wake this one up again.
But i hope you can reassure me a little bit more.
This high load kind of freaks me out, so i would really like to put a finger on whats happening
I have a lot of Neurons running (at least 15+) with very low load averages, always under 0,10
I also have a lot of (newer) Neurons running (some 20+) with very high load averages, like @cristian mentioned, way above 1,20
I haven't got influxdb running on those, and i'm not doing weird things as far as i know.
The only obvious difference I can find is that in the low-load unipi's ther's still the old drivers called NEURONSPI, and in the high-load unipi's they are called UNIPISPI.
I'm not sure this is the culprit, but it seems that the OS version is not really an issue
I have Debian stretch on the older ones, with low load, but i have also stretch installs that show the high load.
All unipi's with Buster have the high load for sure, but they're all UNIPISPI according to dmesg
Is there anything you are aware of that justifies the load difference between UNIPISPI and NEURONSPI?
Or do i have to look further... Or should i really not worry about this?
Most of these unipi's are in production environments long drives away, so if there's something to be fixed i would try to get that done before they break...
Thanks a lot, Tony, Fireware Netherlands

I looked into your package pinning suggestion.
apt-mark hold raspberrypi-bootloader
apt-mark hold python-tornado
apt-mark hold raspberrypi-kernel
before an upgrade at least prevents things getting broken
so at least there's a temporary prevention scheme
Hi Tomas,
Thanks for the suggestions... i'll keep an eye on the git issues ticket, do you want to keep this one alive here too?
Do I understand correctly that it's just a question of pinning the packages you mention too keep my running (remote)neurons safe for now?
i'm so happy I did the upgrade on my desk first, instead of doing it on the remote sites already
i have to say that normally i do apt-get update/upgrade on a regular basis on most of our systems without giving it much thought, so it's good to know that in this case it's a bit more dangerous :/
i'll get back to you after i tried an upgrade with pinned packages...
cheers, tony
here's an example flow that should work:

Hi guys,
I would like to tag along on this one
if i start out with image UniPian-Neuron-OS-2018-03-09.img all works fine out of the box
Evok fine everything fine
But when i just apt-get update / apt-get upgrade things get broken
Does anybody know where i need to look for this?
My guess is that its a kernel thing... it breaks after i reboot, not before taht
under here i have both "good" and "broken" log blurbs
thanks and greetz from holland
all is fine:
