description |
While my system is apparently idle (I'm not running anything that would hammer the CPU) there is still very high use of the CPU, though not by any user task. This screenshot might help explain:

This means that the CPU speed is kept at 2.13GHz whereas in breezy it would be scaled back, making the machine cooler and quieter.
A description of my system follows, i think the only thing i changed from a stock install was to use the fglrx driver:

http://www.zorq.net/dump/screenshot-050206.png
See how the CPU usage is at 70% but the total of the usage by user tasks is below 10%. top was run as a normal user, the same thing happens when run as root.
This means that the CPU speed is kept at 2.13GHz whereas in breezy it would be scaled back, making the machine cooler and quieter.

Try running without fglrx to see if that changes anything. I can get any help from the kernel devs unless you can reproduce this without the non-free module. |
