This is 4.6-stable on a HP EliteBook 8530w (demsg below). $ sysctl hw.setperf hw.setperf=5
I wonder how the 5 got there. I am not setting it; acpi is disabled (because boot hangs with acpi enabled), apmd is not running. Note how the kernel is confused (or lied to?) about the CPU's possible frequencies. Is that relevant to the hw.setperf setting?
