If you possess an Intel NUC running a Linux distribution that exhibits a load of 1.0 or greater while idle, it is likely that you are encountering a bug associated with the USB-C PD controller. This issue appears to be specific to the Intel NUC 10, as it has not been observed in NUC 11 or NUC 12 models. Notably, this problem also occurs on Proxmox systems.
Edit or create the file /etc/modprobe.d/blacklist.conf
on your host system (Proxmox or linux distribution) and add this:
blacklist tps6598x
After this, run this in the terminal:
sudo update-initramfs -u
Reboot your system and the high load should be gone.
