CPU usage constantly at 100% in Jaunty laptop

I've used Ubuntu (Jaunty / 9.04 is the version in question) in my development laptop for last two years. For two days my CPU constantly has 100% usage. I can see in "htop" and "gnome-system-monitor" that Firefox 3.5 and Xorg is competing at the top for CPU resource. If I kill Firefox, the CPU usage still remains at 100%, so I don't think it's Firefox causing this. I tried restarting a few times but that didn't help either. My development experience has been very bad for last two days.

"Try bumping to Karmic now that it's out. The intel video regression has been fixed.

Since I can't read: You're using ATi card right? Is this flgrx or the ati driver? If you didn't install anything and didn't choose the proprietary driver, the answer is ati.

Try bumping to Karmic anyway; you may want to do a clean install. If it's worse or the same as Jaunty, roll back to Intrepid or try another distribution.

(Not that Karmic doesn't have its own issues.)"

"disable effects and see if that alters anything with behavior...?

disable addons for firefox, see if something on that is triggering the behavior?

Sometimes I end up renaming ~/.mozilla to ~/.mozilla.bak and see if a fresh slate makes Firefox behave. I've had a lot of situations on Linux where Firefox starts acting up (usually with playing flash videos on YouTube) where I end up doing this and a lot of wonky behavior goes away.

Export your bookmarks first, though, so you can re-import them."
