If I'm not mistaken, kworker is a kernel task used to defer work from interrupt handlers into a task context.

There used to be 1 kworker per cpu but workqueue design has changed. You can learn by reading Documentation/workqueue.txt in the kernel documentation package.

Usually, kworkers are used by device drivers, you could maybe check if downgrading your kernel helps and narrow down the issue to a particular release.
