Nice catch. Does this affect all Thunderbolt peripherals with MMIO BAR? It sounds like it does.

More abstract questions for thought (not necessarily expecting any answers):
- Why did they do this, why does Windows ignore the reserved region, and why only Lenovo?
- Could this suggest Linux needs to be added into the certification requirements someday?

The thing I love about Ice Lake is it will hopefully give the OEMs less chance to mess up the Thunderbolt implementation than with external chips. However, clearly mistakes can still be made.
