Bug: Something causes kworker cpu to get stuck at 100% while not really doing anything which in turn causes unnecessary boosting and power usage.

Instead I think this CPU usage is not normal and is related to the well-known kworker bug:https://bugs.launchpad.net/ubuntu/+source/linux/+bug/887793
The solution for me and for many others was, first of all, find out the "gpe" that is causing the bad stuff with something like:
grep . -r /sys/firmware/acpi/interrupts/
and check for an high value (mine was gpe13 - with a value like 200K - so, you have to change it accordingly, if differs). After that:
So
grep . -r /sys/firmware/acpi/interrupts/
To find the culprit then..
Fixed with the following inserted into config go file

echo disable > /sys/firmware/acpi/interrupts/gpe69 2>/dev/null
