Public bug reported:
Sometimes, when resuming from suspend, my wifi won't come back on. When
I check the logs, I see:
[103165.388663] iwlagn 0000:03:00.0: RF_KILL bit toggled to disable
radio.
but the hardware kill switch is definitely off. I've tried toggling it
off and on, and suspending in between, but nothing seems to affect it.
The only way I've found to clear it is to reboot the machine.
