I did not get any thousand value mentioned in the archwiki. How could I deal with it?

Re: kworker has 100% cpu usage

Please wrap the output in "code" tags, not "quote" tags.
Also elaborate on the issue. Is the load permanent, frequent, sometimes? Can you spot a pattern like high RAM, I/O (disk or network) load?
Does this also happen w/ eg. the lts kernel?
