Hi there,
I have a HP dv6000 notebook, and am running an Ubuntu 10.10 installation via Wubi. I recently upgraded to 10.10 from the previous release (which I had no problems with at all), but now I am experiencing CPU usage running in between 75% and 100% at all times, right as I boot into Ubuntu and regardless of how many programs are running. I have checked all the running processes, and all seem to be normal ones. The CPU frequency is constantly jumping around in between 800mhz, 1ghz, 2ghz, and 2.4ghz. There doesn’t seem to be a performance issue, but my fan is constantly running on full power. I should point out that CPU usage while using Windows Vista is perfectly normal, and I do not experience these problems while in Windows. Please let me know if you can help me to fix this.
Thank you very much! :)

Yes, it will do this while plugged in and even on battery power.

Nope, just in Ubuntu. It didn't even happen when I had Ubuntu 10.04...

What kernel is Ubuntu 10.10 using ?
Try switching to a different kernel.

You can install a different kernel, leaving the one that is currently running installed,
when you install the new one, you should be able to select the one that you want to boot into
at the time that you boot up your computer.

How do I manually install a new kernel? I did it before through the update manager, but now unfortunately it tells me that everything is up to date...

Did you do the update to 10.10 through the update manager, cause I have never had one done that way work correctly. Maybe do a fresh install from an .iso. I don't know what is is about the online update but in atleast three seperate cases from 9.04 to 10.04 failed to work correctly and 10.04 to 10.10 failed to work correctly as well :ranting:

When I upgraded from 10.04 to 10.10 I did it through a fresh install from a .iso. However, I am not sure as to how to manually download or upgrade a kernel.

Thanks, but this appears to be instructions on how to compile a custom kernel. I just need to maybe install another one that they have already made...?
