Bug Description
I just did a clean install of 9.04 on a Dell Inspiron 6400 (dual core 64 AMD). This laptop has been running versions of Ubuntu since 6.10 with no issue of this type. I used 9.04 Beta without this issue occurring. Presently both cores are running between 45% and 95%, but with *no* obvious program requiring this amount of processing power. I have checked the GNOME System Monitor, Top and Htp- all users and processes examined and I cannot find anything to account for this usage. Gconfd is occasionally using 20%. Both cores are running at 55-56C (highly unusual on this machine as they generally stayed at or below 42C on all previous versions.

Hello,
I can confirm the same behavior on Dell Latitude d820. The Latitude d820 has Intel Core2 Duo CPU, so it is not an architecture related issue. I have seen this strange behavior for this laptop also in Fedora Core 9 and 10.
