iwlwifi/iwlmvm dies on resume when rfkill is set
If I switch my laptop into airplane mode (hardware switch) and then suspend and resume, my wireless is dead on resume and it spews all over the kernel log (see below). I can rescue it by switching airplane mode off and then suspending and resuming again. This problem has existed on all kernel versions I've tried, although I haven't tried a 4.0 kernel yet. --Andy [70699.024982] iwlwifi :03:00.0: RF_KILL bit toggled to enable radio.
