I've isolated the problem to commits on 14.09 and emulators/rtc.

The world is from 17.09
mplayer-gtk-esound-0.99.5_2 port built on 10.09 with rtc support
rtc-2004.02.24.1_4 port was built on 7.09

With kernel from 13.09 there's no problem.
With kernel from 14.09 with rtc.ko loaded I get instant reboot;
With kernel from 14.09 *without* rtc.ko loaded
(/usr/local/etc/rd.d/ start) all is OK.

After rebuilding rtc the system doesn't reboot anymore.

Please add a note about this in src/UPDATING.

At a _very_ first glance, the only file changed on 14.09 that affects
directly rtc is src/sys/sys/conf.h, but of course I might be wrong here;
other might be src/sys/kern/kern_event.c src/sys/kern/subr_witness.c

     sys/sys              conf.h 
   Add three spare fields to reserve room so we can MFC the in-progress
   work on safe device removal at a later date without breaking binary
   compatibility on the RELENG_5 branch.
