Description of problem:

it does boot a while, asks for password for luks encrypted filesystem and then logs:

microcode: CPU0: AMD CPU family 15 not supported

many, many times.

i do not have the exact lines and module line handy, because it did not make it to disk, older kernel report the following, but continue to boot.
