However, LTTng 2.0 supports only kernels 2.6.38 and more recent at this
point. There are a couple of upstream commits you might need to backport
to get it to work with 2.6.33.

Yannick: I think you have those patches somewhere, can we publish them
on the lttng.org website. If you can just send the tarball bundle in
reply to this email, we'll take it from there.
