OK, 9... so that's probably the d90;
  $ ag d90:
      418:#define MSR_IA32_BNDCFGS 0x00000d90

The Intel book says 'IA32_BNDCFGS Supervisor State of MPX Configuration' which I think is pretty new, so I don't know what it's doing trying to do it on a Westmere; ccing in Eduardo and Paolo.

    Don't think so, I actually added it because I thought it would solve something
    I can re-try with out it if needed(with the debug messages).

Worth a go, but if it's that MPX stuff I doubt it.
