[ 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 xtrx-dkms:
$ sudo apt install xtrx-dkms
Load the module:
$ sudo modprobe xtrx
The same procedure should be repeated on linux-6.8 to test for possible
regressions.
[ Fix ]
Patch from xtrx-dkms upstream
(https://github.com/myriadrf/xtrx_linux_pcie_drv/commit/dfae8d33501d46861cd25e13957775b5f626b2a6)
-debian/patches/0005-fix-build-error-with-kernel-6.10.patch
[ Regression potential ]
We may experience regressions in systems that are using the xtrx
drivers, especially with kernels >= 6.8 kernel.
