So in this case the serial output during boot is only coming from a serial-port redirector in the bios, the "stty com0 115200" probably doesn't change anything, and the serial output in multiuser is via init / /etc/ttys > Now, if I change boot.conf to direct output to the serial terminal with: >> stty com0 115200 >> set tty com0 > > Now, when the system boots, at the INITIAL boot prompt, ONLY the serial > console (tty0) keyboard input works.

Can you try kernels between known-good and known-bad (or maybe you have something in /var/log/messages*gz) and look for when this started appearing? A diff of dmesg between serial and non-serial boots might give some clues This maybe implicated: >> vga1 at pci3 dev 3 function 0 "Matrox MGA G200eW" rev 0x0a >> wsdisplay at vga1 not configured >> -----Original Message----- >> From: Ted Wynnychenko >> Sent: Thursday, June 23, 2022 5:19 PM >> To: misc@openbsd.org >> Subject: No login prompt on console ttyC0 after boot >> >> Hello >> >> I have been following current since 5.6, and had been pretty good about >> updates until this last year (issues not related). >> >> Anyway, I asked about updating, found some suggestions that it would >> work, >> and decided to blaze ahead.
