Which version of Red Hat are you running, and which kernel version? There
is a known bug in Red Hat 7.1 retail and SBE that causes oops in NFS. If
you upgrade to the latest RH7.1 errata kernel, this should go away. If you
are running an earlier release of Red Hat, make sure you are running the
latest errata for that version.
