[ 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 intel-usbio-dkms:
$ sudo apt install intel-usbio-dkms
Load the module:
$ sudo modprobe
The same procedure can be repeated on linux-6.8 to test for possible
regressions.
[ Fix ]
Apply patches from intel-usbio-dkms from Questing release:
* debian/patches/backport-fix-build-against-kernel-6.17.patch
[ Regression potential ]
We may experience regressions in systems that are using the usbio-
drivers, especially with kernels >= 6.8 kernel.
