With 4.8.0-2.gb49afc4-default from Kernel:HEAD I no linger see the kernel WARNINGs, but still don't have the wifi toggle functionality that was present in 42.1 - I see the following logged to dmesg: [ 69.179586] atkbd serio0: Unknown key pressed (translated set 2, code 0x88 on isa0060/serio0). [ 69.179589] atkbd serio0: Use 'setkeycodes e008 <keycode>' to make it known.
