I didn't say that. (It may or may not be true: I haven't tested.) All I said
was that your kernel was old *for Ubuntu precise*. Debian squeeze (like
Ubuntu lucid) is another story.

No, the advice is to build .deb packages of OpenAFS for squeeze; either
version 1.6.15 or some older version with security patches (and any other
patches you are interested in) applied on top. Ben actually suggested the
version in wheezy-security as a starting point; that's indeed more likely
to backport cleanly to squeeze.

My suggestion to upgrade the kernel was based on your statement that the
system was running Ubuntu precise; it does not apply if you're running
