I already replied to this last night: "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 " > > Bruce, can you point Feye to this patchset? > > Scott >
