I was getting those as well. I remembered something I used to do to fix it but had to dig into my notebook. Try this:
Make this file:
sudo nano /etc/modprobe.d/sp5100_tco.conf
Put this in the file:
blacklist sp5100_tco
hit ctrl+o to write
enter to save
ctrl+x to exit
Then
sytemctrl reboot
I don’t see those messages anymore. As well as journal warnings.
If this fixes it for you I will come back and clean this thread up and make a new one as the original has been marked solved. Some are going to say there is a better way to do this and they are right i just can’t find it anymore. If it works it works!
