I found the exactly same problem on installing Ubuntu 10.10 Maverick i386 Desktop Edition.
Here are some of my settings.
Installed on : an 5G EXT2 partition on a 8G USB disk.
etc/apt/sources.list : all changed to http://shadow.ind.ntou.edu.tw
CPU : Intel i7 670
RAM : 4G
Using application when updating : Only Firefox
Another to mention : there is always and only 1 CPU running 100% since boot, is that normal?
