FC2 randomly maxing my CPU


For some reason when doing something minor (as far as the CPU is concerned), like surfing the net, I notice the fans on my notebook start going crazy. Looking at the computer monitor I notice that my CPU is pegged at 100% for no apparent reason. I have tested it many times and turned on the monitor when I turn the computer on. The CPU usage goes from 0-10% usage instantly to 100% and flatlines there no matter what I do (logout, shut programs, etc).

I can reproduce it whenever I want. It always does it after the computer has been on for about 15-20 mins. The only way I can fix it is to reboot the computer. The computer runs fine with no apparent slowdowns. I can't see anything obviously pulling the CPU from the application list. I am out of ideas right now.

Any ideas what is causing this? Would upgrading to FC3 help this? I plan on upgrading at somepoint but don't know if this would fix it.

Will do...

I will post the output when the CPU is acting up. Should be just a few minutes.

Ok...well more problems have arrived.

Now when I try to reboot into Linux, it seems to bootup fine but right before it gets to the login screen it seems to freeze. The screen stays black and never actually gets to the login screen.

I don't know what its doing right now. Its a dual boot setup so I am currently posting from Windows right now.

Well I just tried to reboot under the older kernel I have installed and it created the same problem.

Looks like it might be a good time to reformat my Linux partitions and reinstall FC3? I guess that would fix my problems.

This should be easy to work around my existing Windows and data partitions that I don't want to format?

bump

I am going to be wiping out FC2 to install FC3. That should fix my problem.

Anyone have any ideas of things that might have caused FC2 to max my CPU like that? When it started happening I hadn't installed, deleted, altered anything which is why it was baffling me.
