Just to make sure I didn’t have something wrong with my memory, and since it is on the grub boot menu, I decided to run the Memtest cycle as well. Given that all the other options didn’t result in a working system, I didn’t have high hopes.
It took about 50 minutes to run a full cycle and did not report a single error.
I’d say its a regular, old, software related problem.
I hope this gets addressed today, I want to be able to work this weekend.
