This may or may not be related, but I thought it best to inform you about what I just saw anyway: I accidentally toggled the physical RF kill switch on my laptop and the result was very much reminiscent of the bug we are discussing (note the QoS and failure to remove key): Mar 22 20:13:47 rigel kernel: [1259943.614216] iwlwifi 0000:03:00.0: RF_KILL bit toggled to disable radio.

No RF LED, nothing. However, unlike the bug we are discussing, reloading the iwlwifi module fixed this.
