Config
Copy the config-2.6.32-38-generic file
cp -vi /boot/config-`uname -r` .config
Get the libraries required for menuconfig. Not necessary. They were already install.
sudo apt-get install libncurses5 libncurses5-dev
cp .config .config.org
make oldconfig
This will tell me that it set random number generation to enable the x86 architectural RDRAND instruction (Intel Bull Mountain technology) to generate random numbers.
