[ Test case ]
Install the latest linux-6.17 kernel on Noble:
$ sudo add-apt-repository ppa:canonical-kernel-team/ppa3
$ sudo apt install linux-generic-hwe-24.04-edge
Install evdi-dkms:
$ sudo apt install evdi-dkms
Load the modules:
$ sudo modprobe evdi
The same procedure can be repeated on linux-6.8 to test for possible
regressions.
[ Fix ]
Apply patch from evdi-dkms Questing release enabling 6.17
* debian/patches/Fix-build-for-kernel-v6.17-rc1.patch
[ Regression potential ]
We may experience regressions in systems that are using the evdi
drivers, especially with kernels >= 6.8 kernel.
