Philip,
is it possible to push your patch to the Ubuntu distro pool? I'm using
linux-image-2.6.22-14-xen 2.6.22-14.47 and also would like to get
NFSv4 working as I'm using some Solaris in domU and would like to share
ZFS-based storage from it with dom0 Ubuntu.
Thanks!
Karel
PS: otherwise,
Is there already a plan to release the fix for NFSv4 problem? I only ask
as there haven't been any changes for almost a month now. We would like
to migrate a bunch of machines to Ubuntu, and having a working default
kernel would save us quite some work.
Thanks in advance!

Just tried the rebuilt nfs.ko linked above, it appears to work. However
it seems to be causing issues with the nvidia propriety module, it won't
load. I'll post the specifics when I have a second box running to post
from.

You may need to run 'dpkg-reconfigure linux-restricted-

volatile modules ('depmod -a' on a fully booted system should also
work). You can check to see if this is the cause by comparing the output
of the following

sudo apt-get install $IMGPKG=2.6.22-14.46

As promised, here is the fix to unbreak NFSv4 in the 2.6.22-14.47
kernel.
I independently tested:
- Mounting NFSv4 export (sec=sys and sec=krb5)

Here's the nfs.ko compiled against 2.6.22-14.47. Make sure that if you
use this you first back up the current one in /lib/modules. You can

The patch above also applies cleanly to Feisty's linux-
source-2.6.20-16.32 kernel and builds. The system boots successfully and
this bug is not reproducible with the patched kernel. Other NFSv3 mounts
continue to work based on my limited testing.

It should be obvious from my description above, but I wanted to
specifically mention that this regression makes it impossible to mount
two directories from the same block device with different options. An
example of a case that worked in Edgy but no longer works in
Feisty/Gutsy is using sec=sys
