Bisection now points to:

6d74743b088d116e31fe1b73f47e782ee2016b94 is the first bad commit

    NFS: Simplify O_DIRECT page referencing
    
    The O_DIRECT code shouldn't need to hold 2 references to each
page. The
    reference held by the struct nfs_page should suffice.

 I was going to revert that from 3.5.0-rc3 to confirm that my
problem with backups was gone, and then give it more extended
testing to prove firefox downloads were ok, but 6 of 11 hunks
failed, the code has changed and I'm not familiar with it.

 So, for the moment I'm not 100% sure that this is indeed the
problem.
