Hi,

I have been trying to export an reiserfs partition on NFS. I can mount it 
remotely and even create files on it, but I always got a kernel oops when 
trying to remove any file. I have also tryied to export another partition, 
formatted as ext2 (but keeping my root fs as reiserfs), but the problem has 
persisted.

The releases I'm using here are ReiserFS-Progs version 3.6.4, Util-Linux 
version 2.11z and NFS-Utils version 1.0.1. I have also tryied with different 
versions of Util-Linux and NFS-Utils, and have tested with linux-2.4.20, but 
NFS kept the same behaviour.
I did a google' around and I saw many similar posts, but couldn't find any 
patches. Does anyone have any idea about existing patches to fix that?

Below follow the steps I use to reproduce the bug, and attached goes .config, 
dmesg and ksymoops output.

Thanks in advance,
Lucas
