Processor overhead

[Enrico Cavallini]

When I start my ASUS Z53J F3JC with the wireless switch set to OFF the Duo T5500 CPU is constantly overloaded to 70% and more.

If I move the switch to ON load of every core goes down becoming regular.

Maybe a kernel bug?

I forgot this point: wpa_supplicant e network manager are the application out of control

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.
