And yet, there is still the issue: non-working rfkill.
Actually, I did some more testing here and found that rfkill only fails to enable wifi on the first attempt after booting with wifi disabled (disabled before shutdown). I.e. - enable wifi/shutdown/boot + wifi enabled on boot + rfkill button successfully toggles wifi state - disable wifi/shutdown/boot + wifi disabled on boot + first rfkill does *not* enable wifi + second rfkill does successfully enable wifi + subsequent rfkills successfully toggle wifi state dmesg attachment to follow.
David, could you install openSUSE-42.1 kernel onto 42.2 system, boot it, and check whether rfkill really works as is? I guess rather it's in other piece.
Sure, will do later today - thanks Takashi. -- You are receiving this mail because: You are on the CC list for the bug.

Forgot to mention this testing was done with 4.8.0-2.gb49afc4-default (kernel:HEAD). -- You are receiving this mail because: You are on the CC list for the bug.

I installed 4.1.34-1.g67a2e9d-default from the 42.1 kernel repo. rfkill doesn't work correctly, so it does appear to be affected by user-space, as you've suggested. Still, I don't see the kernel workqueue warnings with the old kernel. -- You are receiving this mail because: You are on the CC list for the bug.

I created a quick test KMP containing a few upstream fixes for dell-wmi. It's found in OBS home:tiwai:bnc1004052, will appear shortly later in
http://download.opensuse.org/repositories/home:/tiwai:/bnc1004052/ openSUSE_Leap_42.2/
Let me know if it works.
Thanks Takashi. I've installed your dell_laptop-kmp-default build, and updated the Dell keyboard hwdb. The "dell_wmi: Unknown key 153 pressed" messages are no longer seen, but the workqueue WARNINGs are still encountered on rfkill, resulting in system lock-up: [ 35.094885] atkbd serio0: Unknown key pressed (translated set 2, code 0x88 on isa0060/serio0).
