solution - fix udev rule - Re: C-states only used _with_ load on Acer Extensa 5220 Kubuntu

[Dennis Jansen]

Okay, I think I've found the problem.

udev seems to have occupied the cpu somehow trying to rename the
wireless device created by the b43 driver.
Because the problem disappeared after I changed a udev rule.
Also before I had a 30 second hang while starting that I thought was unrelated.

So no more problems after commenting out in
/etc/udev/rules.d/70-persistent-net.rules

# SUBSYSTEM=="net", DRIVERS=="?*",
ATTRS{address}=="00:xx:xx:xx:xx:xx", NAME="eth1"

Hope this will help other people.

Just weird nothing showed up in top or powertop...
