Modern HP servers, among others, may display the following warning when booting RHEL7+ and associated flavours:
The BIOS has corrupted hw-PMU resources (MSR 30d is 330)
This can be safely ignored. However, if it bothers you, you can disable it thus:
- Boot machine to RBSU (F9).
- Press CTRL+A.
- Select "Service Options."
- Select "Processor Power and Utilization Monitoring."
- Select "Disable."
- Press F10 to save and exit.
