Could this be your problem:

r276986 | nwhitehorn | 2015-01-11 18:10:07 +0100 (søn, 11 jan 2015) | 8 lines

MFC r265329:
Disable ACPI and P4TCC throttling by default, following discussion on
freebsd-current. These CPU speed control techniques are usually unhelpful
at best. For now, continue building the relevant code into GENERIC so that
it can trivially be re-enabled at runtime if anyone wants it.

Relnotes:       yes

% svnlite diff -c 276986 sys/amd64/conf/GENERIC.hints

Does it work if your unset or remove those lines from /boot/device.hints?
