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 3.16.6-031606-generic with same result (see attached). Same behaviour, fsck never finishes and ls hangs. Tried mainline 3.14.22-031422-generic and problem is gone, fsck finishes in several seconds, no problems with ls, machine and VMs running normally since.
