https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D225782 --- Comment #1 from Conrad Meyer <cem@freebsd.org> --- If this is also true on CURRENT, it looks like a buggy BIOS. Your BIOS isn= 't reporting P-states via ACPI or you would see a second positive number inste= ad of "/-1". It's possible the BIOS bug also breaks P-state setting. If a BI= OS update is available from your vendor, consider applying it. If this works on CURRENT, great. I don't support stable branches, so I wou= ld just unsubscribe from this bug in that case. In either case, I'd suggest rebooting and just not setting dev.cpu.0.freq (leaving the machine in P0). At idle, FreeBSD enters power-saving C-states= and won't consume any more power than if you were also downclocked. --=20 You are receiving this mail because: You are the assignee for the bug.=
