There are various PM scripts which might be trying to turn power save on and off based on certain events (specifically applying or removing external power). They can't really tell whether it was you which turned off power save or if it was turned off due to an event, and I'm sure they aren't smart enough to know about module options they should check. The errors are safe to ignore. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1394163 Title: Unable to turn powersave for wlan0 off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1394163/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
