Public bug reported:
Binary package hint: network-manager
Use case:
I tell network-manager to disable my wireless, expecting this to gain me some
battery life or because I am entering a no-radio zone (airplane, hospital etc).
My laptop has no hardware switch or led to indicate wireless status, so I
assume network-manager has switched it off
Current behavior:
The radio interface is still active and the number of interrupts reported by
powertop for the ipw2200 driver goes up drastically. The "disabled" interface
thus uses more power and misleads the users. Using rf_kill manually disables
the radio and stops the interrupts, as expected.
I am using 2.6.22 on gutsy with all updates.
Proposed solution:
Make network-manager aware of rf_kill state and disable radio when wireless is
disabled.
