But a stream of encrypted 0's (or 0xFF, as seems to be the case here) still adds precisely as much entropy as the key has to the pool. And if a buggy RDRAND is your only source of "entropy" (I know that shouldn't happen in practice), then the entire stream of random numbers is trivially predictable.
