(In reply to Konstantin Belousov from comment #51)
Hm, no, we apparently do not fall back to printf() if no control terminal is
assigned.  Please do the following: in sys/amd64/amd64/trap.c, near the end of
the function trap(), in the fragment

        if (uprintf_signal) {
                uprintf("pid %d comm %s: signal %d err %lx code %d type %d "

replace uprintf() with printf().  The messages should appear in the dmesg.
