It should all work provided kgdb plays nicely. We used to be able to compile in both xmon and kdb and select at runtime which one gets used. > That issue aside would it be useful to have xmon+kgdb?

Obviously only one or the other can be used at any given time. Well, xmon_init(0) will do a detach. However, I don't see that it is needed; there is plenty of flexibility to choose to have xmon or not using the CONFIG_XMON_DEFAULT config option and the xmon= boot command line option.
