Thread-topic: Numa=on broken? 
All,
It looks like numa=on is broken.
I have tried with the tip of the tree, with the changeset 14676 (which
fixes the numa=on problem) and the two patches that Ryan sent out. 
I am running with boot options acpi=on and numa=on.
I am running on an ES7000 with 2 nodes (2 cells of 8 processors and 32
GB memory each).

Thanks
Raj
PS. We(Unisys) are going to start running our weekly tests with default
numa=on. This weeks' tests brought out this problem.
