I only have 12.2 here and it initializes the wrong amount which will cause a
panic if you rely on the getting the amount of memory from how the memory ctlr
regs are set up.

The last time I really looked at what DINK was doing to the mem ctlr was back on
12.0 so my info is stale now.  Sounds like Tom has the most current, detailed
info on what DINK does.  Chances are, Sergiy, is that you'll  have to roll up
your sleeves and dig into it.
