Comment 43 for bug 181996

(Storm)
I was using the nolock option since then - that means work with locking disabled,
wich - of course - worked.

On 10.02. I enabled locking again to give it a try. No problems since then.
Kernels are 2.6.24-23-generic on both client and server
nfs-kernel-server and nfs-common are 1:1.1.2-2ubuntu2.2

I still don't think it's a new problem - it just shows up in very special cases,
whch we don't know. Over here it disappeared as randomly as it appeared before
- and you still have it. When did it appear in your site ? Which changes did you make
before ?

If you post, have a look at https://wiki.ubuntu.com/KernelTeamBugPolicies
Over here, we're on our own now.
