What were you trying to do?
Determine the CPU speed of a machine.
What's wrong:
I got different values at different times.
What should have happened:
This appears to be be because the machine's CPU has frequency scaling,
and the "cpu MHz" line of /proc/cpuinfo indicates the frequency the
CPU is currently running at. athinfo should either indicate the
actual maximum processor speed, or both the maximum and the current.
Please describe any relevant documentation references:
