[Bug 2111377] Re: sl-modem-dkms FTBS in Noble with the linux-6.14-hwe kernel
Hello John, or anyone else affected,
Accepted sl-modem into noble-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/sl-
modem/2.9.11~20110321-19ubuntu0.1 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-6.14 kernel on Noble:
$ sudo add-apt-repository ppa:canonical-kernel-team/ppa
$ sudo apt install linux-generic-hwe-24.04-wip
Install sl-modem-dkms
$ sudo apt install sl-modem-dkms
Load the modules:
$ sudo modprobe slusb
$ sudo modprobe ungrab-winmodem
The same procedure can be repeated on linux-6.8 to test for possible
regressions.
[ Fix ]
Apply patch from Debian (https://salsa.debian.org/debian/sl-
modem/-/blob/master/debian/patches/fix-linux-6.12-ftbfs.patch):
* debian/patches/fix-linux-6.12-ftbfs.patch
[ Regression potential ]
We may experience regressions in systems that are using the sl-modem
drivers, especially with kernels >= 6.8 kernel.
