This is a known issue upstream, reported at http://bugs.lttng.org/issues/814 . It is due to Ubuntu kernels now having a backported fix from more recent kernels, which happens to break an API used by LTTng. More info at that link.

Unfortunately, this cannot be "fixed" upstream because it would then break support for older kernels. A more proper solution is in the works for future versions (using UBUNTU_RELEASE_ABI), so this shouldn't happen again (famous last words...)

But for now, it seems the only solution is to patch the modules, using the patch from Michael in comment #3. The packages from the stable PPA https://launchpad.net/~lttng/+archive/ubuntu/ppa include this patch, so they should build fine on 14.04. Would be nice if this fix could be pulled in Ubuntu proper, so that at least the lttng-modules-dkms package from the repo installs correctly.
