Bug#410160: nfs-kernel-server: NFSv4 inconsistent client behaviour on etch

[Jonathan Schmitt <jonathan.schmitt@informatik.uni-augsburg.de>]

This bug is not restricted to creation of files. It also occurs in the 
following scenario:

user@clientA:~$ echo A >> test.txt
.. pass some time ...
user@clientB:~$ echo B >> test.txt
.. pass some time ...
user@clientA:~$ echo A >> test.txt
...

only gives

root@server:/home/user# cat test.txt
A
A
..
(updates from B are omitted)

or even worse
root@server:/home/user# cat test.txt
A
  A
  A
  A
B
(updates from B are somehow garbled)

It has been reported and is currently also discussed here:

Kind regards,
Jonathan
