kworker too busy
by JohnHendry from LinuxQuestions.org on (#51KPD)
Just today I find I have about 7 clusters of processes comprising groups of "cpuhp<digit>, migration/<digit>, ksoftirqd<digit>, kworker<digit>, kworker<digit>-kblockd" and I have no idea how to control this, which I suspect is totally useless behaviour just to use free cpu time. It's very distracting as it makes a noise, too. It never used to do it.

- migration/3
- ksoftirqd/3
- kworker/3
- kworker/3-kblockd
