Are you running powers? Do you use c-states? What happens if you boot in (instead of switch to) turbo mode? --- Sent using a tiny phone keyboard. Apologies for any typos and autocorrect. Also, this old phone only supports top post. Apologies.

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 eve= n if powerd is running. It looks like some bug in interaction between cpufreq and Turbo mode of this CPU. --=20 Best regards, Lev mailto:lev@FreeBSD.org _______________________________________________ freebsd-hackers@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscribe@freebsd.org"
