Does not work on xSeries 336 for me. Shows that CPU have HTT, 2 logical
CPU. But does not launch "logical" CPU. When I've added #define
MPTABLE_FORCE_HTT 1 into /sys/amd64/amd64/mptable.c I've seen detection on
second CPU, but it hangs solid after "Timecounters tick every 1.000 ms".
Just after that in single processor mode mpt0 is begin to initialize.
Sincerely, Maxim M. Kazachek
