This is normal with hardware like the ipw2200 that has a hardware rfkill line. >> And rfkill-input will soon be enhanced to let the user configure it to do >> something different if he wants.

Actually, all the users have to do right now is to have rfkill-input loaded. It *already* kicks all devices online when you release the master rfkill switch. >> Thanks.

Some network drivers want to do it themselves, so now it will be the job of every driver to know whether it should do something or not. To test your platform to know if you will need to do something, just comment the rfkill->toggle_radio in rfkill_suspend, and check if your radios are still transmitting when you suspend. I really doubt any laptop has that problem, though. -- "One disk to rule them all, One disk to find them. One disk to bring them all and in the darkness grind them.
