The boot process is not setting the interface names properly.  Whats even more fascinating about this is I have upgraded other machines (although they are newer) from 9.3 to 11.0-RC1 and they worked just fine.

I just noticed, all the systems that upgraded and worked properly are amd64.  This one is i386.
