If you have an AMD cpu and you install the 3.4 kernel you will get this microcode error.

microcode: failed to load file amd-ucode/microcode_amd.bin

Go to here: http://www.amd64.org/support/microcode.html
and download the latest package.
The instructions for installing the patches are included in the download.
Works great.
