There was also an article in the latest issue of this new newspaper that
replaced _On_Communications_ (I forget the name, I think it might be
_Network_World_) that claimed that a bug existed in the 286 which was
causing network processors using that MPU to "lock up".  Unfortunately,
the article was very unclear on what was going on; and according to the
article, Intel denied any problem existed, claiming manufacturers just
hadn't followed the documentation properly, whereas the manufacturers
interviewed claimed there was a bug in the processor.  Does anybody know
what is going on with that, and if it is the same problem referenced
above?
