Is there any documentation for the graphics hardware? Is hardware available on the market in the US?

Is it reproducible? You can trigger reading from the RNG with: sysctl kern.entropy.gather=1 I don't think I've changed anything in the past month or so that would affect it -- more likely, this is a stochastic (and perhaps transient) failure of the RNG hardware. I also see a likely bug in the VIA cpu_rng code judging by the Padlock documentation -- should be easy to fix, once the air here cools down enough to boot up my VIA laptop without setting fire to the table.
