Comment 8 for bug 118808

I am also running the latest snapshot of madwifi-ng, and indeed I get ~10-20 wps.
BUT... while wireless in on, my CPU still spends ~70-80% in C2 while completely idle.
As soon as I turn wireless off (in Network Manager), the CPU goes back to ~99% in C3/C4.

Could it be a hardware characteristic of my laptop?
Or maybe the lack of cpuidle support as Matthew Garrett suggested?
