How To Investigate Failed To Start Load Kernel Modules Error?

Failed to start Load Kernel Modules was a constant occurring during my system boot. I finally sat down and decided to investigate it.

The very first task is figure out which modules are causing the problem. For that we need the PID of process where modules fail.

The important line here is Main PID: 29552 (code=exited, status=1/FAILURE). We have the PID and now we can check journalctl for the faulty modules.

Now it became clear that the VirtualBox drivers are at fault. This is how you can investigate future system module failures.
