If I remember correctly, all the SMP CPUs on the same bus should give the same values (since they are synchronized and reset from the same signals). The discrepancy may appear on machines with multiple bridged front-side buses, essentially the NUMA machines (such as those with over 4 Intel CPUs). -SB _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
