Comment 7 for bug 463379

I suspect Firefox as causing X to freeze. Sometimes mouse is movable but non-functional, sometimes it is also frozen. Keyboard is active when mouse is movable. However, the system is very unstable and most likely is on its way to a full-freeze. For example, I can't log out or restart the system via the desktop menu.

System stays up varying amounts of time after Firefox is started. System can run for days (and largely idle) if Firefox isn't started.

Would like to contribute to this thread - what can I do to help narrow down the issue?
