If you can, can you update the kernel to a stable/recent version (i.e. longterm 3.10) and e2fsprogs to a current version, re-create a fresh file system and try to reproduce again? If you still can, can you try to figure out which order of syscalls is causing the corruption? Or anything else that might help to figure out the root cause? In general, using a rather old kernel and user space tools and pointing to an issue isn't going to help you much. Cheers, Bernd
