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.
