After Upgrading Ubuntu 11.04 to 11.10 on my Dell D420, there is always 100% CPU
usage on one of the two processor cores.
When core 1 has 100%, then after a couple of seconds core 2 has 100% and the
other falls into idle.
This happens all the time after the upgrade (core 1, core 2, core 1.......).
Changing over to gnome window manager does not change anything, same happens
when using the guest account.
Today I have startet my laptop with a live stick of 11.10.
Here I also have the problem, that one core always has a CPU usage of 100%.
