Public bug reported:
Every day, when I wake up my ThinkPad x220 from sleep, its wifi doesn't
come back. "rfkill list" shows:
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes
and dmesg shows:
[32330.371510] iwlwifi 0000:03:00.0: RF_KILL bit toggled to disable
radio.
toggling the hardware kill switch has no effect. Reloading the module
doesn't resolve the problem. Suspending and resuming again doesn't
resolve the problem. The only way I've found to get back online is to
reboot.
Oddly, I haven't been able to reproduce this by suspending and then
resuming immediately. It seems to happen when the machine is left
suspended for a period of time, like overnight.
