In the kernels I have tested, it seems to boot fine with CONFIG_SMP on
or off.  The extended patch series does initialize the exception
handlers earlier than without the extended patch series.  It is possible
that there may be additional logic added by the Fedora Kernel vs the
kernel.org kernel which is what kgdb and the extended kgdb patch set is
regression tested with.
