I've compiled the kernel with # make buildworld -DNO_CLEAN and copied over the new kernel with # cp /usr/obj/usr/src/sys/GENERIC/kernel /boot/kernel/kernel The kernel boots fine as: FreeBSD c720-r314251 12.0-CURRENT FreeBSD 12.0-CURRENT #2 r314251M: Tue Jan 2 12:53:31 CET 2018 guru@c720-r314251:/usr/obj/usr/src/sys/GENERIC amd64 but: while the current date is read with the correct time, the year is 1970: # date Tue Jan 2 1970, 13:45:24 CET One can set the date/time with the date(1) command or ntpdate. The debug messages are (the first line is from boot, the others from the date or ntpdate): # grep DEBUG /var/log/messages Jan 2 13:43:02 c720-r314251 kernel: BCD DEBUG: atrtc_gettime() entry Jan 2 13:43:02 c720-r314251 kernel: BCD DEBUG: atrtc_gettime() entry Jan 2 13:44:00 c720-r314251 kernel: BCD DEBUG: atrtc_set() entry -- Matthias Apitz, ✉ g...@unixarea.de, ⌂ http://www.unixarea.de/ 📱 +49-176-38902045 Public GnuPG key: http://www.unixarea.de/key.pub
