Pretty much a standard Origin.  I suspect the problem might be related to
machines which only have a single physical CPU, that was the only common
thing between all the Origins on which Linux fails.  And indeed I don't
think we ever used such a small configuration for testing at SGI ...

Nick, did you observe any interesting differences to your failing Origin
configuration?

Btw, Origin UP kernel is definately broken ...
