<br>
Based on the sessiond logs and the content of "/lib/modules/`uname<br>
-r`/extra" there was clearly a problem on lttng-modules-dkms installation.<br>
<br>
Most of the time, the culprit is the lack of memory at compile time. How much memory<br>
is installed on your system?<br>
<br>
Please reinstall the package:<br>
sudo apt-get install --reinstall lttng-modules-dkms<br>
<br>
Make sure to take a good look at the logs.<br>
<br>
Cheers<br>
