In the dmesg, the lines: bcm2835_cpufreq0: on cpu0 bcm2835_cpufreq0: ARM 600MHz, Core 250MHz, SDRAM 400MHz, Turbo OFF disappeared, and the log shows: /etc/rc.d/powerd start powerd: no cpufreq(4) support -- aborting: No such file or directory As what seems to be a consequence, the system became much slower. Everything came back to normal when I copied the old rpi2.dtb to the new /boot/msdos/ I tried the rpi2.dtb from the lastest snapshot FreeBSD-12.0-CURRENT-arm-armv7-RPI2-20171109-r325595.img and cpufreq(4) disappeared again. What I am missing ? TIA Claude Buisson
