Kworker/10:2+events driving up load to about 18...?

Yesterday, I saw this kernel process in top that was at 100% and system load went up to around 18. Is there something I can do about this?

I’m not sure whether that’s related, but I recently also saw

iwlwifi 0000:00:14.3: Microcode SW error detected. Restarting 0x0.

in journalctl

Not really. You could at least determine which function consumes so much cpu power…

  1. That records the calls for 10 seconds:
sudo perf record -g -a sleep 10
  1. That will let you view the record:
 sudo perf report --input=perf.data
  1. Or use this for watching:
sudo pref top -g -a
