I don't know. The workaround would be to disable that service, though
I'm not sure if you can manage that from a live CD. Interactive boot is
probably broken these days, I don't know if systemd implements anything
like it.

The bug here probably isn't really that microcode_ctl fails, but that
the failure is fatal to boot - it shouldn't be. Microcode updating
should be entirely optional and if it fails, boot should just continue.
It's entirely possible this is what happens in F15, if you look at it
carefully. Looks like this is filed as
https://bugzilla.redhat.com/show_bug.cgi?id=715118 .

Ah - which also gives a hint to avoid it: blacklist the 'microcode'
module. That should be possible from the bootloader, I think.
