There are two issues we know of: 

- the temperature issue, if that causes a failure you should see the LED 
flashing regularly (~ 1 or 2 sec period) - we're going to produce some boards 
with the temp issue fixed and swap out boards for anyone who's having an issue 
- this will take a couple of weeks 

- most versions of rngd seem have an issue with the way it checks for 
randomness of the entropy source (see the email exchange we had here 
yesterday) - this may be what you're seeing: rngd is shutting down - I'm going 
to release a software change that further whitens the input to rngd, hopefully 
this coming weekend
