Thanks for the explanation. This looks just magic and for sure an idiot I
am to still prefer Intel CRA^H^HPUs for stability. :-)

Btw, if I had a system that experienced such a problem, I would configure
the thing for the magic FIFO to simply divide the thing by a integer
value. Could be 2 there with memory used as PC100. The simplest, the less=
=20
risky to trigger hardware bugs, in my paranoid opinion. ;-)
