Created attachment 9625 [details] Buildroot with util-linux config examples and logs In my .config file I use BR2_PACKAGE_UTIL_LINUX=y because of it I have build fail on old kernels (4.19.269; 5.4.179). On kernel 5.10.19 and 6.1.26 works ok. Looks like old kernel should use old util-linux (more old then v2.39)? Steps to Reproduce: git clone https://git.buildroot.net/buildroot && cd buildroot [Put my files to buildroot/configs/] make clean make pc_x86_bios_defconfig_4_19_269 make Build Date & Hardware I use last buildroot from git (a89a632833dca00beb7443ef540571b281703ae1). 18 Jul 2023. Ubuntu 22 5.19.0-46-generic See my config files and corresponding logs.
