That shouldn't really be an issue for the most part.  It would only
impact you if you're hitting issues in an area where the config
options differ between releases, and those are fairly uncommon.  You
can try using koji bisect to start with to at least save yourself some
time.

Basically, the best bet is to copy the fedora kernel config into a
kernel git tree and just use git bisect, make bzImage, make modules,
make modules_install, make install.  If you want to save some build
time, trim the config to not include the bajillion modules we ship.
