Your HWRNGDEVICE is not correctly set. Refer to http://fios.sector16.net/hardware-rng-on-raspberry-pi/ for more on using the Pi's hwrng device.

You may also wish to install haveged, which adds additional system entropy very nicely...

I have rng-tools installed and added HRNGDEVICE=/dev/urandom to /etc/default/rng-tools to no avail.
If found this command and I guess it tells me how much I have? Not sure, but I included it just in case it helps.
cat /proc/sys/kernel/random/entropy_avail 3116
