Comment 21 for bug 660746

Hi Miroslav,

your post gave me the idea to try to just disable the wireless powersaving for now:
sudo mv /usr/lib/pm-utils/power.d/wireless ~
(Just moving it to somewhere save.)

This works for me. Now wireless works fine on battery.

This is of course just a workaround. We need to find out what powersave attempts cause which cards to fail and why...
