Unless someone already had this exact bug, I doubt someone can help you from just what you said.

Does it reload every two seconds on every page? On some pages? On one specific page? Did you try seeing what happens if you go to other pages that are almost code-less? (or at least not likely to be buggy, like www.google.com?)


What have you installed on your N900, and did you enable either extras-testing or extras-devel? Do you have the power kernel, or still on the normal one? Have you changed any files anywhere, or deleted anything, shortly before this problem arose? People need to know these things to be able to figure out what might be causing your problem.
