The script is /etc/init.d/ondemand
It sleeps for 1 minute and then sets the scaling
governor, based on availability, in the following order:
interactive
ondemand
powersave
See also:
$ ls -l /etc/rc?.d/S06ondemand
lrwxrwxrwx 1 root root 18 Mar 8 09:51 /etc/rc2.d/S06ondemand -> ../init.d/ondemand

That is normal, and is turbo mode. Example:
$ sudo turbostat -i 3 --msr=0x199
CPU Avg_MHz %Busy Bzy_MHz TSC_MHz MSR 0x199
