Not sure I understand which version of lttng-modules you are currently using. Can you share with us the result of 'modinfo lttng-tracer'? Could you pastebinit (or equivalent) the log produced by the lttng-sessiond in verbose mode (lttng-sessiond -vvv). Please take a look at the bug reporting guidelines [1].
