Did these people actually have a _working_ rng before? I saw a report of a mac user, for which the rng disappeared. But the previously "detected" rng didn't work either. (Work as in produces sane random numbers). So there actually wasn't a rng available all the time. -- Greetings Michael. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
