If you are concerned with that RNG, we can easily drop it from the LRNG. The testing documented in the writeup disable the Jitter RNG to ensure that only the LRNG IRQ collection is tested. The conclusions regarding timeliness of the seeding, the prevention of draining the entropy pool are performed without the Jitter RNG which implies that the Jitter RNG can be dropped without harm.
