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.
