This might be related to the following bug:
https://bugzilla.redhat.com/show_bug.cgi?id=706611

In the past I used to just get a warning for my Athlon MPs since they
don't support updating the microcode. In rawhide this changed to failing
in a loop instead (which I think is a bug). I ended up uninstalling the
microcode_ctl package on that machine.
