Please try to remove all lttng modules from your
/lib/modules/3.0.4/extra directory, go to your lttng modules tree, make
clean, make, and, as root, make modules_install.

This should fix it. I expect that currently your modules are built
against the wrong kernel tree.

If it does not fix it, investigate whether your /lib/modules/3.0.4/build
symlink points to a kernel tree (or kernel headers) that match your
running kernel.

Best regards,

Mathieu
