Did you by chance run System > System Testing?

There is a bug in Ubuntu (edit: 10.04) that will cause the CPU to skyrocket to 100% once you close the window after System Testing using the process "backend." This doesn't happen during testing, or any step in particular, and can happen even if you choose "Skip this test" all the way through it. And it only triggers once you close the window.

I'm not sure why there hasn't been a fix for this yet, other than to just avoid running System Testing..

I had one of the cores in an AMD Phenon II x6 going at 100%. Top showed the backend process was the problem, and I had just recently checked out the system testing app. Killing it solved the probelm, thanks!
