Hi, ‘make defconfig’ did a very good job, thanks for the advice. My idea of using .config of the host distribution was completely wrong. LFS is up and running now, and booting is much faster than with my host distribution. I still wonder where the error message came from - I was assuming that the kernel should compile in either case after using the standard configuration tools. Regarding the (working) configuration that is a result of ‘make defconfig’ and customization with ‘make menuconfig’, I have two questions: - How do I know if one or more modules/configuration settings are missing (even though the kernel runs)? - How can I tell whether there are extra modules or options turned on that are not really used in my system? Thanks a lot,
