[ Test case ]
Install the latest linux-6.11 kernel on Noble:
$ sudo add-apt-repository ppa:canonical-kernel-team/ppa
$ sudo apt update
$ sudo apt install linux-image-6.11.0-12-generic \
linux-modules-6.11.0-12-generic \
linux-modules-extra-6.11.0-12-generic \
linux-headers-6.11.0-12-generic
Install lttng-modules-dkms:
$ sudo apt install lttng-modules-dkms
Load the module:
$ sudo modprobe lttng-test
[ Fix ]
Patch the code to properly support the new linux 6.11 ABI.
[ Regression potential ]
We may experience regressions in systems that are using the lttng
debugging tool with the new 6.11 kernel.
