Some more test I did.


New install of the latest Debian version. Confirmed that the 3 kworker: 
Events_unbound processes are present. If the 3 processes are not at the 
top of the list, grabbing a window and dragging it around the screen 
rapidly will send those 3 processes to top.


Installed Nvidia drivers (550) from Debian repository, After reboot *the 
3  kworker: Events_unbound processes are NOT there. *There are kworker 
processes in the list but not "events_unbound". No amount of dragging a 
window around on the screen brings these processes to the top. No CPU 
power spikes will using browsers. I still need to test screen sleep and 
locking as this is where I was have problems with the Nvidia driver.


Regards,

Benjamin
