If you're interested in the types of bugs that are present in modern CPUs, AMD makes their errata documentation publicly available. (As far as I know, Intel's errata are not public. Edit: See tedunangst's comment below for a correction.)

The errata for AMD Family 12h Processors (A-Series APU, etc.): http://support.amd.com/us/Processor_TechDocs/44739_12h_Rev_G...

AMD should be commended and the guy who found the bug especially. This is how I got into software from the hardware world, in a complex custom system sometimes the bug is in the hardware.

Intel includes errata in updated spec sheets for each CPU.
