Sure, I wasn't expecting that.

Indeed, looking into the output provided by the 6328SE and some 12 core MagnyCours CPU I forgot the number of, was helpful. I *think* I fixed the cpuinfo now for new AMDs which provide 0x800001e topology info. Please give the latest snapshot from https://cygwin.com/snapshots/ a try.
