Hello and thanks for reading this!
my PC has the kworker problem and I digged a bit with https://askubuntu.com/a/421916
But sadly I don't know how to interpret the backtrace...
So I continued and did run sudo fwts that showed a lot of fails...
As I understand them, they are related to acpi problems.
From there I tried to disable the acpi powerbutton function with https://askubuntu.com/a/362931/1382969 , but this did not help.
Do you have an idea how to fix this?
Here is the backtrace and the fwts summary:
