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
was not in the expected working state. 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.
