Ext2fs strange errors on -CURRENT.

[Neh]

I'm having some problems using ext2fs.
I have a mounted ext2 partition. It mounts ok.
I can do "ls dir" and it show me the contents.
But when i type "ls -l dir" for example, i got messages like:
"no such file or directory"

I can do "cp" to that partition, can do "rm" in some file, but copying from
there or deleting recursive, like "rm -rf" show me "no such file or
directory"

some outputs:

I checked it on 5.4-STABLE and it's working ok.

I have used ktrace to see what's going, but i can't say what is, so i
included the output of both "ls" and "ls -l" here:
