Ooops - no NVRAM in your scope, you have the one with the discrete RAM chip.
The other problems I know of that could reasonably lead to RAM corruption
are power supply problems, and the shutdown sequence.
... and the discrete RAM write protection circuitry on this scope. This
protects the RAM from spurious writes when the 5V rail drops under some
cutoff voltage.
I'm sure none of that is material for your scope as it's failing kernel
tests, which should give you at least a starting point for what's failing,
if now how and why.
