Yes, we took our 9845 from OSx4.4 to 5.0d without doing any hardware
upgrades first.  We suffered random kernel panics and machine checks (a
couple per day).  We were apparently one of the first sites to do this
and it took Pyramid a while to conclude that CPU rev levels were the
problem.

They eventually swapped all 4 CPUs and data caches (20+ boards) which
cured our problems.

Now we're looking at a OSx5.1 upgrade.  Anybody got war stories about that?
