What's it about? some kinda new intel advanced power domain stuff (RAPL is "Running Average Power Limit"), to limit CPU power consumption... that message just means its not supported by your hardware (or VM), so the intel_rapl driver is exiting. totally harmless albeit mildly annoying. you can blacklist the intel_rapl driver to get rid of it. -- john r pierce, recycling bits in santa cruz
