First, this isn't gconfig-specific. xconfig or menuconfig should have the same behavior. At least I see it in xconfig also. > Is this done for some special reason? Or can they be turned off? All 3 of the KALLSYMS kconfig symbols are under the kconfig menu prompt: "Configure standard kernel features (for small systems)", which is not enabled in ps3_defconfig AFAICT (unless Geoff's is modified from that I can see/test in linux-next). All that you need to do is enable that config symbol (called CONFIG_EMBEDDED) and then you can modify the KALLSYMS config symbols. HTH. -- ~Randy
