Ok, so it's definitely something about your configuration. Maybe something in the 11,2 support code chokes on single-chip configs, I don't have one of them to test, both mines are dual chip (ie. quad core). But it does look like a regression that should be bisectable, so let me know went you're done there and what you get. Cheers, Ben.
