1. Why the SMP and NON-SMP kernel ? Just one or the other is needed, not both. SMP = multi-processor or hyperthreading only ( though may be fine with non SMP .. I haven't examined the .config or the sources ). 2. Why the manual Sytem.map to System.map-2.4.21-27.0.2.EL symlink, also note the spelling.
