freebsd stable - Jan 2018 - FreeBSD 11.1-release - verbose boot causes the machine to restart

Ok, this I haven't seen before.
I just installed FreeBSD 11.1-release on a quite new machine[1]. The machine is
an ASRock BeeBox-S 7100U, a quite "normal" NUC-form machine with a
i3-7100U (Kaby Lake) and an internal SSD.
Installation went great (I only had to manually copy /boot/boot1.efi to the
correct EFI partition. Yes - there are other operating systems on the internal
SSD), and the machine boots and works normally.

However, if I select verbose boot from the boot menu, the kernel starts spitting
out kernel messages and after a while the machine restarts.
Afterwards (after a normal boot) there is no sign of this unusal activity either
in dmesg output, /var/log/messages or /var/crash.

Is this something developers want to know more about? If so, pointers on howe to
debug this further is appreciated.
Details (including dmesg outpuyt from a normal boot) on the FreeBSD page[2] of
this machine.

Is it a panic reboot?  If so you can try setting the loader or sysctl
option to not reboot after panic or drop to debugger option.

I don't think so - there are no indications of that.
