Hi Harald,
It looks like there might be a problem with the C7-M ... Michael reports that if he sets LOCK_PREFIX to "lock;" it works, but that shouldn't be necessary for a uniprocessor.
I'm wondering if we have to revive the OOSTORE hack, or some other workaround. It is of course hard for me to track this down since (a) I don't have access to the CPU documentation, and (b) I work for Intel now, which limits the amount of time I can realistically spend on this.
