AH, thats a shame to hear - was hooing it had worked OK for you!

Will give that a try next week - when remote form the box I dont want to
crash it, so no such tests at the weekend, but hen I am back will see.
The lockup from Thursday was aan idle-lockup, and that hasnt happened since
I chnaged the BIOS settings. May reenable those one at a time to see if
any single one is reposible, unless anyone has any insight. Much hunch would
be that SMT may be OK to re-enable as tat has nothing do do with loading,
whcih the other two do.
