The pseudo-random number device driver is not operational because the self test failed.
After processing a published National Institute of Standards and Technology (NIST) test vector for the
Deterministic Random Bit Generator (DRBG) algorithm, the device driver
did not produce the expected pseudo-random data. This failure might indicate
that the cryptographic software or hardware is not working correctly.
The processed NIST test vector was: Hash Drbg, Sha-512, Count #0.
