Which made me wonder: Shouldn't they be the same, as the cores run from the same clock? Could it be a bug in the bogomips calculation which could make some of the short time-out stuff fail? Could this be related to the tsc synchronisation stuff mentioned in the lost ticks - TSC timer thread? Regards, Robert Boermans. PS nothing actually fails on my system because of this, I just thought it was odd. Although I do sometimes get the clock runs at double speed problem but only after at least one day uptime, but I reboot most days for games anyway.
