Yes, I hit something similar:
http://www.spinics.net/lists/linux-nfs/msg46047.html 'nfs: disallow duplicate pages in pgio page vectors' http://www.spinics.net/lists/linux-nfs/msg46048.html 'nfs: can_coalesce_requests must enforce contiguity'
seem to stop the GPF's/crashes, although there's still something else going on with a corruption I'm seeing every so often.
