Problem Description:
While attempting to execute the test scenario defined at http://ltp.sf.net/nfs,
I am able to generate Kernel BUGs. I'm not sure if this is JFS or NFS
related...I figured I'd open in JFS first. Here is the trace output:

===================================================
Steps to reproduce:
Execute the test scenario described in the 2.5 NFS testplan located at
http://ltp.sf.net/nfs . The test scenario is modified to have only one client
and to have the NFS server and client be the same machine....using the
localhost interface.
