13.1 on a toshiba laptop
Online Update says everything up to date.
After logging on, the processor is being used at 35 to 40 percent. This will continue even overnight if left alone.
top shows a PID of 52 or 53 at first, and after a while the process seems to shift to PID 1931 or so.
The command is shown as kworker 0:0 or sometimes 0:1
I tried kill 1931 but I think that because it is a thread, the command had no effect.
Can someone direct me to a way to find and stop the process?

Hi
Use the pstree command to see what is starting the worker… there are lots of options, but the following should help;
pstree -p
I can’t seem to get pstree to show the low numbers such as in the 50s

Hi
Those a kernel workers, you need to trigger a backtrace and see if you can figure out what it’s upto…
echo 1 > /proc/sysrq-trigger
Open a couple of terminals and tail the messages log, then as root user run the above command and inspect the backtrace in the log to see if can narrow it down.
Thanks for the reply. The laptop belongs to a friend who lives across the country from me, so it’ll take a little time for us to get on the phone and try your suggestion.
