Unfortunately, it introduces a circular dependency when I build with my distribution's (Arch Linux) configuration: $ curl -LSso .config https://github.com/archlinux/svntogit-packages/raw/packages/linux/trunk/config $ make -skj"$(nproc)" INSTALL_MOD_PATH=rootfs INSTALL_MOD_STRIP=1 olddefconfig all modules_install ... WARN: multiple IDs found for 'nf_conn': 99333, 114119 - using 99333 WARN: multiple IDs found for 'nf_conn': 99333, 115663 - using 99333 WARN: multiple IDs found for 'nf_conn': 99333, 117330 - using 99333 WARN: multiple IDs found for 'nf_conn': 99333, 119583 - using 99333 depmod: ERROR: Cycle detected: nf_conntrack -> nf_nat -> nf_conntrack depmod: ERROR: Found 2 modules in dependency cycles! ... The WARN lines are there before this change but I figured they were worth including anyways, in case they factor in here. If there is any more information I can provide or patches I can test, please let me know! Cheers, Nathan
