Description Bastien Nocera 2017-12-02 15:17:18 UTC
Using kernel-4.14.0-0.rc8.git1.1.fc28.x86_64 and newer, the WiFi firmware crashes while trying to connect.

This likely affects more than just the F27 version.

Those firmwares fail:

This will require this patch to be backported to every version of Fedora where linux-firmware is being updated, as well as adding the necessary conflicts with older kernels.
