How to disable “Processor Power and Utilization Monitoring”: – enter BIOS (press F9 during boot) – press CTRL+A (Service Option is hidden by default) – select “Service Options” -> Processor Power and Utilization Monitoring -> Disable
Edit: DL380 Gen9 is also affected with this problem. The solution remains the same (disable Processor Power and Utilization Monitoring)

There really isn’t any fix needed. It is just an informational message. The system is reserving performance counters for system management and the kernel wants to own all the performance counters regardless. You can disable the ProLiant management features if you really want to stop the message. Other than printing the message during boot, there isn’t any negative impact on the system or performance.
