            Bug ID: 278123
           Summary: multiple tty support disappeared in current on Alder
                    Lake about the last half of January
           Product: Base System
           Version: CURRENT
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: portmaster@bsdforge.com

On the following hardware, an upgrade from
FreeBSD 15.0-CURRENT #0 main-n267640-7a4d1d1df0b2:
Thu Jan 18 04:04:32 UTC 2024
to
FreeBSD 15.0-CURRENT #0 main-n268793-220ee18f1964:
Thu Mar 14 02:58:39 UTC 2024
resulted in the inability to use any other tty than
ttyv0. ps waux | grep getty, indicates getty is
servicing all of them, as does ls /dev indicate that they
are all there. /etc/ttys and /etc/gettytb are identical
to previous versions of CURRENT. I have nothing in rc.conf(5)
that would have any affect. The use of any other tty than ttyv0
is also unavailable while booted to any of the FreeBSD install media.
My most recent attempt is from:
FreeBSD 15.0-CURRENT #0 main-n269036-6baddb6b1176:
Fri Mar 29 10:19:43 UTC 2024
Which fails in the same manner.

The hardware affected is as follows:

CPU: 12th Gen Intel(R) Core(TM) i3-1215U (2496.00-MHz K8-class CPU)

IdeaPad 3 17IAU7
