In this particular trace, NFS walked a linked list and found the pointers weren't pointing where they should be. Could be memory corruption by something other than NFS, or it could be a bug in NFS. Hard to say. The 'Tainted: G W' part means something else occurred before this trace (The W specifically). That may be more enlightening.
