Hi all, On using the 5.14 RC6 kernel there seems to have been a regression that prevents the wifi from working on boot. It works on 5.13.x [mostly] fine. I believe this probably needs to be reported upstream but I’m not running an upstream kernel. The failure message is: Aug 22 14:03:40 chuchel …

as the thread links here, but not in reverse - this was discussed at lore kernel org in “[regression] Re: 5.14 rc6 broken for QCA6390 on Dell XPS 13 9310” and fixed before the final 5.14 release
