Comment 30 for bug 297385

Affects me on a Vaio TX47, using Ubuntu 10.04, kernel 2.6.32-26, 32-bit.

Same issue if booting with the hardware switch in the 'off' position, or toggling the wifi kill switch to 'off' then back to 'on'.

I can reliably re-awaken the card with the following command:
$ echo 1 | sudo tee `find /sys/devices -name state | grep ieee80211`

Seems that the killswitch state doesn't transition back to 'on' properly?

state == 2
Occurs when the killswitch is in the physical off position.
Syslog: "NetworkManager: <info> WiFi now disabled by radio kill switch

state == 1
Occurs when the killswitch is in the physical 'on' position, but only after a boot.

state == 0
Occurs with killswitch in the physical 'on' position after wake-from-sleep, or toggling the killswitch from 'off' to 'on'.
