I’ve been struggling with this problem for a while now, and i couldn’t find a working solution.
The kworker process constantly uses 100% of a CPU and blocks everything, I can’t even shut the NVidia down.
I know it’s a known problem in the community, but all the solutions I found (this, for example https://askubuntu.com/questions/176565/why-does-kworker-cpu-usage-get-so-high) seem to pass through the ACPI interrupts manager, which is (apparently) not present on my board.
In my current setting, I have connected to the board a CAN bus and a LiDAR talking through ethernet, which are both using interrupts (as long as I know).
Thanks in advance for any help!
