I am the one who encountered the spinning state manager process and associated
lockups while on NFS home. Since this was on my primary workstation and the
lockups were troublesome (to say the least), I had to migrate to local home to
be able to work.

The bug was easily reproducible (in fact, unavoidable) on my setup, which was:

* openSUSE 13.2
* NFS home against nfs.suse.cz (Netapp)
* KDE4
* Thunderbird, Pidgin, Firefox

I never did narrow down the trigger, but I *suspect* it was clicking on URLs in
Thunderbird and Pidgin, so they open in Firefox. At some point (1-4 hours of
normal usage after reboot) I would click on a link only to find that the system
had become unresponsive because writes to /home were not completing. 

When this happened, a process called 10.100.2.89-man was visible in 'top'
and the load average would rise due to the "spinning".

The following message would appear in /var/log/messages:

> NFS: nfs4_handle_delegation_recall_error: unhandled error -13.

(note, not -10026)

Martin Caj also has openSUSE 13.2, NFS home, and KDE4, but uses a different MUA
and a different IRC client, and AFAIK he could not reproduce -- hence my
suspicion that the issue is related to Thunderbird+Pidging+Firefox interaction.
