Comment 26 for bug 891825

wowo, I believe that "From Linux manual: Options for NFS versions 2 and 3 only. nfsvers=n:" isn't unambiguous at least for me it worked like this. With nfsvers=4 exactly same problems come up as with nfs4. Setting this nfsvers=3 resolves it but downgrades protocol to nfs3.

I remember beating my head to wall last time with this in Maverick. Finally got time to upgrade :-)

I got it resolved with these options:
server:/mnt/mythtv-00 /mnt/mythtv-00 nfs4 defaults,nfsvers=4,relatime,timeo=100,ac,bg,clientaddr=192.168.1.20 0 0
Direct copy of my client's fstab. I believe its bg or timeo=100 option which made it to work. Don't have time to experiment but passing info here.

But this is pain as Ubuntu still don't work with basic things like nfs... I'd like to see slowdown in releases or omit one release to really fix these annoying things.
