When System.map was generated, the kernel used mksysmap to filter the kernel symbols, we need to filter "L0" symbols in LoongArch architecture. $ cat System.map | grep L0 9000000000221540 t L0 The L0 symbol exists in System.map, but not in .tmp_System.map. When "cmp -s System.map .tmp_System.map" will show "Inconsistent kallsyms data" error message in link-vmlinux.sh script.
