I had similar problems when updating from 5.4 to 6.1 because of 
nvidia-driver. After changing the card, the system worked like a charm. 
Later on recompiling nvidia-driver (forgot to deinstall it) resulted in 
the machine crashing and rebooting itself. This happened with a 
non-nvidia graphic adapter installed. I remember hearing that 
optimizations might be the cause of the driver failing.

Hope this helps.
