 Hi Jason, I think Deng Dongdong's patch is a good candidate for a while. Though Don mention another issue
on his Celerone machine so I need to think about the reason for unknown NMIs he observes. I try to get access
to p4 machine tomorrow and test some ideas. Will keep you in touch! (initially I thought to write a long post
about possible hang scenarios but then found they all are crap and I better to check details on real p4 machine
before claiming anything :).
