A bug in the NFS client has been fixed (cf. https://www.rtems.org/bugzilla/show_bug.cgi?id=1284) on the CVS head (will hopefully be committed to the 4.8 branch soon, stay tuned). For people using an RTEMS version earlier than 4.8 rtemsNFS-1.6 is available here: http://www.slac.stanford.edu/~strauman/rtems/nfs/ -- Till
