So far we can only reproduce this bug when the system is resumed from hibernate, not when it's cleanly booted.
The system uses NFSv4 for home directories.
We tried the following kernel versions: 3.2.35-2, 3.2.32 and 3.2.23. We could trigger this bug on all of them.
Maybe the system had an NFSv4 lease from the server before it was hibernated and still thinks it's valid when
it resumes and then hits a bug if it turns out it was no longer valid?
Regards,
Rik
