Re: C2, C3 and bus master activity

Hello

> Sometimes an active WLAN driver causes bus master activity...

Inserted USB, removed WLAN and ieee1394. C2/C3-ratio dropps to 10:90 in 
console-mode. That's better. I don't mind removing ieee1349, but without 
networking the laptop is more or less useless. So i'm f***ed.

No USB in use except the 4 root-hubs (the trackpoint is using PS/2).

I have seen 10:90 on AthlonXP-systems running XFree. That's what i want, even 
if it is a long way to go.

So i only have 2 problems left:

- Is it possible to reconfigure WLAN to cause less Bus Master Activity ? (i 
will ask the ipw2200 guys and grok the code)

- and why is the radeon driver causing ffffffff-Activity ?

Running x without radeon driver is not an option. The radeon driver enables 
powerplay, which in turn saves quite a bit.
