If so, look for possible overheating (CPU > temperature, airflow restricted by wiring, long carpet, bad fan motor > or fan control SW...).

Sensors show nothing special and fans work fine according to my eyes and ears. Hardware just works fine apparently. And if I swap the internal hard-disk to the one on which my old FC5 system is used, I can't get the periodical short hangs (tried for a couple of hours). The symptom doesn't seem to be sensitive to CPU or memory loading. But of course it's not easy to diagnose, as I've upgraded the hardware memory modules, changed disk and installed F8 from scratch at the same time. I'll use another video driver to see (fglrx or X600 as suggested). Will get back when I have something new! Regards, -- wwp
