So I tried to remove all variations from the HAVEGE program. I replaced the “HARDTICKS” macro in HAVEGE with the constant 0 (zero) rather than reading the time stamp counter of the processor. This immediately failed the randomness test.

However, when I used the constant 1 (one) instead, the ent test passed. And even nist almost passed with only a single missed test out of the 426 tests executed.
