I think I did compile with enabled modules. kern-xen-dev:/mnt/kernel/linux # cat .config | grep MODULE CONFIG_MODULES_USE_ELF_RELA=y CONFIG_ARCH_HAS_STRICT_MODULE_RWX=y CONFIG_STRICT_MODULE_RWX=y CONFIG_MODULES=y <<<<<<<< # CONFIG_MODULE_FORCE_LOAD is not set CONFIG_MODULE_UNLOAD=y CONFIG_MODULE_FORCE_UNLOAD=y # CONFIG_MODULE_SRCVERSION_ALL is not set # CONFIG_MODULE_SIG is not set # CONFIG_MODULE_COMPRESS is not set CONFIG_MODULES_TREE_LOOKUP=y I added a new kernel module and was able to see the module added. kern-xen-dev:/mnt/kernel/linuxfs # insmod linuxfs.ko kern-xen-dev:/mnt/kernel/linuxfs # cat /proc/modules linuxfs 16384 0 - Live 0xffffffffc01c1000 (O) I think, on my test machine, by default, there are many modules which get added during boot up, which with vanilla kernel is not happening. Thanks for your input.
