Please correct me if I'm wrong, but this thread's conclusions seem to be:
* network interrupts are an inappropriate source of entropy (see my patch) * headless servers need entropy, but should seek a better solution, such as EGD, hardware RNG, or other kernel entropy sources (but that is a separate task) * TPM RNG is a separate task and, if implemented, should be in drivers/char/hw_random/
