John Dyson has enabled the "Global" bit on some parts of the kernel.
This makes the marked pages immune to TLB flushes.  Could this be the
reason for the P6 Problems ?

I belive there is a bit in a control register that will enable/disable
this, it's probably in locore.s somewhere.

Future will arrive by its own means, progress not so.
