Htop is showing 100% cpu usage on thread 1 , on a fresh install of 17.10

Question

I have a freshly installed 17.10.1 (amd64) , my cpu : Intel(R) Core(TM) i7-6700K , and when I'm running the htop command I see that the first thread is always maxed out (98-100%), although I don't see anything using that much CPU . Is this a bug or just htop messing around ?

Do you get similar if you use top instead of htop? I also would suggest to use turbostat to observe what is going on. — Doug Smythies, Feb 21 '18 at 00:47
There is clearly something going on as You have 3 running apps (1 of which is the htop itself). — Michal Przybylowicz, Feb 21 '18 at 00:48
Well i found out it's a process called kworker (https://imgur.com/w9jBy8X) although it won't die when i try to kill it — Πέτρος Ιωσηφίδης, Feb 21 '18 at 01:13
No, don't try to kill it. Try to figure out what process it is associated with. (which can be difficult) — Doug Smythies, Feb 21 '18 at 01:17

Scroll down to the 2nd answer by mauro. Why does kworker cpu usage get so high?

Everything seems to be running smoothly now. For me it was gpe6F
