Subject: kernel BUG at fs/nfsd/nfs4state.c
Date: Sun, 13 Feb 2011 14:12:06 -0800	[thread overview]
Message-ID: <AANLkTinW7mWsrgwY2JsG9U-Qk1icKyApbdVJvavw4iGZ@mail.gmail.com> (raw)

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
