One of cores at around 90% load

Hi,
I having weird issue on Manjaro, on my Acer 7th gen Intel (2C4T) + nVidia 940MX one of cpu cores is constantly on ~90% load. HTOP and TOP command shows usage but there is no app doing that on list.
Manjaro KDE installed today from manjaro-kde-21.2.3-minimal-220205-linux515.iso as newer would not install. Updated to all packages and kernel to 5.16 but whole system is so laggy. KDE works noticeable slower than usual, games are unplayable. CPU fan on higher settings all the time.
So far tried different kernel 5.10, 5.15 & 5.16, dropping down to tty don’t make any difference, really no matter if I switch to tty before loging in to KDE or after. Tried to stop some services I’ve installed but no joy.

Any idea how to diagnose this?

Regards
Thom

Just checking: how do you see that?


htop from terminal.

conky here

Normaly conky in idle shows about 1% or less.

Is the heavy load always on the same core? Or does it switch core over time?

Mostly is last core no 3 but I seen once core no 2.

In the meantime, i suggest you provide your system information and look for system logs.

I’ve collected some of info but can’t myself see anything here.

I think the problem is solved. Not sure what exactly fixed this but works now.
Manjaro updated and I’ve cleaned thermal compound on CPU and near to it.
2-3 days latter the problem did not exist.

I think the problem was rather thermal than OS problem as similar thing was happening on windows 10. It was not so obvious as windows works slower anyway on this laptop.

Thanks all for help.
