Please give more details: - What's the result of df -T . - What's your libc version? - What's the result of uname -sr - What's the result of ls --version
I'm asking because three possible causes come to mind: - a network file system (mentioned by Paul Eggert), - the multi-grain time stamps introduced in Linux 6.13 [1], - a known glibc bug [2] that affects certain coreutils releases.
