My Lenovo Carbon X1 does not up-scale CPUs correctly with Ubuntu 13.04 using the ondemand governing. Lowering the up-threshold seems to do the trick.
#!/bin/bash
# default with 13.04 is 95
SCALING_FILE=/sys/devices/system/cpu/cpufreq/ondemand/up_threshold
if [ ! -f "$SCALING_FILE" ]; then
echo "$SCALING_FILE not found"
exit 1
fi
if [ $# -ne 1 ]; then
echo "Usage: $0 <throttling percentage>"
echo "E.g. $0 70"
exit 1
fi
limit=$1
if [[ $limit -lt 100 && $limit -gt 30 ]]; then
sudo bash -c "echo $limit > $SCALING_FILE"
else
echo "Invalid value"
exit 1
fi
