I want to add an observation. I upgraded from 16.04 to 18.04 and the first boot already was sluggish and the mouse pointer is slow. First I suspected a baloo_file process to be the cause. It's not. I noticed the fans of my thinkpad spin up. I saw no load on the cpu (as normal user). Also the disk io is low. So what is causing this? Then the sensors still show high temps and it got hot. I noticed also the gpu temp is hot. Then i disabled wayland and rebooted. Still it is slow. Then i booted only into recovery root shell and noticed only as root is a kworker/u16:0 process visible, which produces high load. So now I suspect some other kernel level process is out of control, but I don't know what this kworker process belongs to..
