Like I said, its not a Fedora kernel, and thus not something we can
reasonably support here. The only possible list-relevant bit of info
here would be knowing *why* you're building your own, such that we can
make the Fedora kernel provide what you need so you don't have to, if
possible and/or relevant.

That said, seeing as how a Fedora kernel does boot your system, you'll
probably get a lot closer to a bootable system with your own kernel if
you start with the Fedora kernel config file instead of the upstream
kernel config file, and go from there.
