OK. When you don't set it to OS Controlled, the HPE RBSU chops power 
management out of the ACPI in a way that makes Linux complain about 
corrupt ACPI information.

I realise that you are looking at IPMI, not ACPI, but it does have that 
HPE smell of ugly removal from your view because the RBSU is managing 
it. That could just be coincidence of course.
