your computer crashes instead of powering off properly.
-config CPU_FREQ
- bool "CPU Frequency scaling"
- help
- Clock scaling allows you to change the clock speed of CPUs on the
- fly. This is a nice method to save battery power on notebooks,
- because the lower the clock speed, the less power the CPU consumes.
-
- For more information, take a look at linux/Documentation/cpufreq or
- at <http://www.brodo.de/cpufreq/>

- uses a sysfs interface instead. Please note that some drivers do
- not work well with the 2.4. /proc/sys/cpu sysctl interface,
