Warning do not appear in dmesg with recent kernels (4.1* containing http://kernel.opensuse.org/cgit/kernel/commit/?id=e30b876cd96fb14ce4a94d6fbf0ac2c95782c127 ). As for "state manager process spinning" I am not sure if I am able to help as I am not using nfs home (instead having it mounted as /mnt/home) and using it mainly as backup/easy way to publish stuff on users.suse.cz - and I have not encountered issues which mcaj described - I mean I would like to help but some reliable way to trigger issue would help.
