Thanks (*^__^*)

You can't change out the kernel version / tree and expect to use the full
functionality provided by the linux-yocto kernel. In this case there are
changes to NFS and rpc to support alternate rpc ports being used to support
usermode NFS. You would need to port and test the patches for this
which can be found on yocto/standard/base

Cheers,

Bruce
