Disable CPU frequency scaling / stepping #65

Open jyundt opened 7 years ago

jyundt commented 7 years ago

Related to tumblr/collins#550, CPU speed is incorrectly captured during induction as a result of CPU frequency scaling. When lshw is executed (as part of adding a new node into collins), the CPU speed can vary depending on the load of the server.

Ideally CPU scaling would be disabled and lshw would report the correct / maximum frequency of the processor.
