got this bug shortly after a fresh boot into 2.6.38-rc4 a nfs client
at the time was logging into its nfs home
the server is a 32bit setup running debian squeeze
the client at the time was 64bit debian squeeze (also running 2.6.38-rc4)
and the output below is from the server
let me know if you need more info and I can do tests if required
