I would boot from an installation USB / CD (preferably the one you set the
machine up from) and go into Rescue Mode, and see whether the hardware still
continues behaving the same way.
That means you're testing it with the versions of kernel / modules / boot
loader / etc as you did when you set it up, without any updates.
There are two possible outcomes:
If the result confirms the hypothesis, then you've made a measurement.
If the result is contrary to the hypothesis, then you've made a discovery.
