[Bug 2091563] Re: lttng-modules-dkms FTBS in Noble with linux-6.11-hwe kernel
Hello Massimiliano, or anyone else affected,
Accepted lttng-modules into noble-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/lttng-
modules/2.13.11-1ubuntu1.1 in a few hours, and then in the -proposed
repository.
Please help us by testing this new package. See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed. Your feedback will aid us getting this
update out to other Ubuntu users.
If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
noble to verification-done-noble. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-noble. In either case, without details of your testing we will
not be able to proceed.
Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in
advance for helping!
N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

[ 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
The same procedure should be repeated on linux-6.8 to test for
possible regressions.
[ 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.
