It sounds like your system is running well.  I'm not much closer to
narrowing this down.  My problem could still be any of the following:

    * software bug (e.g. in powernow-k8 driver) - from my experience
this is still the most likely.  I'm dreading it, but maybe I'll have to
install Windows and see if I can reproduce the problem there.

    * faulty hardware - I've ruled out the motherboard, but maybe the
CPU or some other component is bad

    * hardware design bug - there could still be some relevant design
difference between the K8T800 chipset your tested and my K8M800

Thanks for your help Pascal.
