Public bug reported: backport-iwlwifi-dkms which is included in the kernel is broken for HWE 6.17. The backport iwlwifi driver is not needed for 6.17, the in-tree driver is sufficient. For Questing 6.17 this works as expected and the linux-modules-iwlwifi-<release>-generic package is empty. However the Noble 6.17 HWE kernel is broken and ships a (broken) module in that package.
