If you can boot at all in some way you are already 95% there as you can
investigate what went wrong, maybe even why, and fix it.  Here are
suggestions:
  -- run 'package-cleanup --dupes' (package-cleanup is supplied by
    yum-utils) and use that with --cleandupes if needed; sometimes
   --noscripts too may be well advised
  -- run 'package-cleanup --problems' and fix issues if any
  -- run 'package-cleanup --orphans' and think what to remove
  -- run 'rpm -qV >& /var/tmp/report' and see what is there; reinstall
     packages if necessary
  -- run 'yum update' as this also may help to smooth some rough edges

If after all of this there are no more reports of any package troubles
and you still cannot boot in a normal way then carefuly comb through
you logs and fix things as required.  Re-running corresponding package
scripts can be of help as possibly something failed there the first time
around.

All of the above should not be needed but sometimes things go south;
so document all troublespots you found and attach that information to
your bugzilla report.
