Bug Description
Upgraded a NFS client to 14.10. Server is running FreeBSD 10.0, no changes on server from when client was running 14.04. Client is using NFSv3 over TCP.
Client hosts virtual machines - first virtual machine starts ok, second virtual machine starts but machine needs to fsck and reports timeouts, left overnight still cannot complete fsck. A simple "ls" of the NFS share hangs.
3.16.0-22-generic kernel kern.log generates warning and the Oops with null pointer dereference (see attached).
Tried mainline 3.16.6-
Tried mainline 3.14.22-
