Hello FreeBSD, I'm installing latest 12-ALPHA4 on new MiniPC with Celeron J3160 CPU. It is 1.6GHz CPU with Turbo up to 2.somethingGHz. If I enable Turbo mode, after booting to FreeBSD it locks at 480MHz according to dev.cpu.0.freq, and simple "openssl" test confirms it. If I disable Turbo mode, after booting to FreeBSD it locks at 1600MHz even if powerd is running. It looks like some bug in interaction between cpufreq and Turbo mode of this CPU. -- Best regards, Lev mailto:lev@FreeBSD.org
