Created attachment 257203 [details] dmesg from kernel 4.9 Hardware: ThinkPad Yoga X1 gen 1 04:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a) Plot: I bought recently a TP-LINK Archer C7 v2 router and started to play with alternative firmwares. Since LEDE was not satisfying me in terms of wireless performance I decided to give DD-WRT a try. After installation of the newest firmware I setup VHT80 network + WPA2 personal and tried to connect: - on KSPP kernel 4.11 computer freezed immediately, I couldn't even check tty for OOPS - on generic 4.11 it also got a freeze, but I was able to switch to ttyS2 and make a picture of the OOPS - on generic 4.9 kernel I was able to save dmesg output (see attached file), eventually didn't connect - but also didn't freeze The freeze is 100% reproducable. I didn't try to play with module parameters nor wireless network settings, but I can do it tomorrow if necessary. I use Arch with testing repositories enabled. Was connecting through network manager. Also I tried another computers, one with Atheros 9280 wifi card, another with Intel 7260 (non-ac version). Both connected successfully. Once again - let me know if I can provide you more details. I don't know what information would be useful to you and don't have time to try random combinations of module params / wireless network settings.
