Phoronix: Following Buggy AMD RdRand, The Linux Kernel Will Begin Sanity Checking Randomness At Boot Time
The Linux kernel will begin doing a basic sanity check of x86_64 CPUs with the RdRand instruction to see if it's at least returning "random looking" data otherwise warn the user at boot time. This stems from a recent issue where AMD's RdRand behavior with some hardware (particularly, buggy motherboards) could have borked RdRand issues...
