Hi Robert,

Thanks for that, I did not notice that in the spec. I am currently using 64 bit format unconditionally and this must be what is going wrong. 

Thank you so much for that.

How are you formatting the addresses in the TLP? The PCI Express spec 
says that for addresses below 4GB the 32-bit addressing format must be 
used (you can't use the 64-bit format unconditionally). It could be that 
is what is making the chipset unhappy.
