Public bug reported:
When accessing nfs4 mounts I get kernel 2 Oops.
On the server I am running the latest feisty version:
ii nfs-common 1.0.12-4 NFS support files common to client and serve
ii nfs-kernel-ser 1.0.12-4 support for NFS kernel server
On the client I am running the latest gutsy version:
ii nfs-common 1:1.1.1~git-20070709-3ubuntu1
NFS support files common to client and server
ii nfs-kernel-server 1:1.1.1~git-20070709-3ubuntu1
support for NFS kernel server
The Oops does not happen after the mount, but after some random read /
write time using the share.
