Comment # 1 on bug 942178 from Takashi Iwai

Through a quick glance, I could find only one patch that is relevant with NFS4,
and it's not clear whether this really affects.

I created a KMP for NFS modules with the patch revert in OBS
home:tiwai:bnc942178 repo.  The KMPs are being built now, so grab the KMP
corresponding to your running kernel, install it and retest.

After installing the KMP, check whether the updated nfs is used, e.g. by
checking "modinfo nfs | grep filename".  It should show the update path,
/lib/modules/3.16..../updates/....  

If this works, the culprit is the patch.  If not, it's somewhere else.
