Do you think this is an artifact of your using LFS
or from some aspect of your chroot?

In any case, this should fix it.
Please confirm:

diff --git a/tests/rm/one-file-system b/tests/rm/one-file-system
index c8e11eb..d1821c5 100755
--- a/tests/rm/one-file-system
+++ b/tests/rm/one-file-system
@@ -28,6 +28,8 @@ require_root_
 cleanup_()
 {
   umount "$other_partition_tmpdir"
+  # On some systems, the above fails, yet unmounting a/b works, so...
+  umount a/b
   rm -rf "$other_partition_tmpdir"
 }
 . "$abs_srcdir/other-fs-tmpdir"

If that doesn't help, please show me what df -h prints,
or just send the relevant line from /proc/mounts.
