[Lu Jingchang-B35083] 
  Are you using kernel version of next-20130529? With the same .config, it seems boot crash with IPv6 enabled after I update to the git tree, but not on next-20130528 and before. Disable IPv6 option makes NFS boot successfully on my board. By the way, the failed message on my side is not the same as above. Thanks!
