** Description changed:
The symptoms I see are very similar to bug 193970 but with a different
wireless chipset. I can't tell whether it's the same problem or not, so
I'm filing a separate bug as it's easier to merge them than to tear them
apart.
- If I turn off the (physical) RF kill switch after it has been on (either
- since boot or after having activated it manually), the LED never turns
- on and the card doesn't scan:
+ If I turn off the (physical) RF kill switch after it has been on since
+ boot, the LED never turns on and the card doesn't scan:
perseus:[~] sudo iwlist wlan0 scan
wlan0 No scan results
Nothing is shown in dmesg from iwlagn when I turn off the kill switch,
but other RF devices in the system change state, so I can see that it's
working:

[ 1623.090931] sierra: USB Driver for Sierra Wireless USB modems: v.1.3.2
Unloading and reloading the module gets it working, i.e. the LED turns on and
scanning works:
perseus:[~] sudo modprobe -r iwlagn && sudo modprobe iwlagn
perseus:[~] sudo iwlist wlan0 scan
wlan0 Scan completed :
Cell 01 - Address: 00:1C:10:A3:02:15
[...lots of networks...]
+ Once I've done this, I can toggle the switch on, confirm no scan
+ results, turn it back on, and get results again.
