I think that it’s related to the Device-2: Realtek RTL8153 Gigabit Ethernet Adapter type: USB driver: r8152 bus-ID: 2-1.4:3

This only happens when the USB/ethernet dongle is connected to the laptop.

My laptop doesn’t have an rj45 plug and I need to connect to an internal network.

Any suggestion on what to do?

Thank you

A kworker process is a kernel worker process and that points you towards:

  • Faulty hardware
  • a bug in the kernel

so do the following in this order and only go to the next point if the previous one did not solve the problem:

  1. Plug the adapter into another USB port
  2. Change the LAN cable with a brand new one
  3. Install both 5.4 and 5.10 LTS (Long Time Support) and see which one of the two troubles you least. (If you don’t know how to do that, please shout out)
