Hi Szymon,

Based on the sessiond logs and the content of "/lib/modules/`uname
-r`/extra" there was clearly a problem on lttng-modules-dkms installation.

Most of the time, the culprit is the lack of memory at compile time. How much memory
is installed on your system?

Please reinstall the package:
    sudo apt-get install --reinstall lttng-modules-dkms

Make sure to take a good look at the logs.
