I've been having the same problem since May on an Tyan ATX 1668 system
(with a 5 week hiatus when my machine was sent back to the vendor for
repairs, including problems with memory). At the time, Steve
suspected that it was hardware, but this hack does allow me to run SMP
now. Two things in common is that we both have Matrox accelerators
and NCR SCSI controllers. Strangely enough, I did have SMP running
for about a week in early May, but it stopped working about the time I
did some hardware changes.
