Public bug reported:
If I had disabled Bluetooth or WLAN on my notebook and make
suspend-2-ram and resume again, they got re-activated.
This is a bad behavior for various reasons:
1. Network manager got confused, because it still thinks, that WLAN is
inactive - but the WLAN LED is online.
2. I have to disable BT / WLAN again. I don't want to do this over and
over. Often, I suspend my computer only for some minutes, just to bring
in from one place to another (like walking from my home, to the
university - or changing the train). And after that, its annoying to
deactivate BT and WLAN again.
3. If I forgot to disable it again, the WLAN chip will consume power of
my battery (and perhaps the BT too).
It would be better, if the last state got recovered. So if BT or WLAN
was deactivated before suspend, it should be deactivated after resume.
If it was activated, it should be re-activated.
This problem exists still in Jaunty. My hardware is:
WLAN: Intel 3945
Bluetooth: Dell Computer Corp. Wireless 355 Bluetooth
