You have been subscribed to a public bug: The problem appeared when I upgraded my linux kernel from 6.2.0-26-generic to 6.2.0-36-generic. Observing the output of the top command, the processes that show up at the top are : - kworker/0:x+kacpid - kworker/0:x-kacpi_notify
where x changing from 0 to 3. CPU usage of those tasks varies between 20% and 25%.
