Steps to reproduce:
1) Download the latest LTP testsuite
2) Build and install the testsuite
3) Make sure the NFS server daemons are running
4) Export an XFS filesystem to be used for testing, globally, with root allowed.
ex: /mnt/xfs *(sync,rw, no_root_squash)
5) Change directory to where the LTP is installed
6) Change directory to testcases/bin/
7) Execute 'nfs_fsstress.sh' and follow the prompts.
a) Enter your hostname as the server
b) Enter the export filesystem name, i.e. /mnt/xfs
c) Enter "10" for the number of hours to execute.

The oops should occur within 2-3h or so.
