They are not. As the hardware did not change (I did not unsolder
some chips from the board 8-), I guess that's what I'm asking:

How can I tell the kernel that the serials are still there ?

The system boots via serial, and then stops displaying any
kernel output.

Does this note from /usr/src/UPDATING help?

20240715:
        We now lean more heavily on = ACPI enumeration for some traditional
        devices. uart has moved from = isa to acpi so the hints act as wiring
        instead of device = enumeration. Hints for parallel port, floppy, etc
        have been removed.  = Before upgrading, grep your dmesg for lines like:
=             &n= bsp;   uart1: non-PNP ISA device will be removed from GENERIC = in FreeBSD 15.
        to see if you need to start = including hints for the device on isa
        in your loader.conf or = device.hints file. APU1 (but not APU2) boards
        are known to be affected, but = there may be others.

The = problem is also on APU2, and fixing the = hint.uart.0=3D=E2=80=9Cisa=E2=80=9D
got my serial console = back!

FWIW, I've had several reports that APU2 with up of date = firmware diesnot have this issue. APU was the only system to come up = more than once, and the only one made after maybe 2010 or so.


IMHO, it = might me an issue with the bios/efi firmware, I have PCengins APU2 with = a resent firmware = from 
Dasharo.com?

So thanks to all of = you!

I don't know if this note was MFC'ed to stable.
https://github.com/freebsd/freebsd-src/commit/63e282288= ed84387d2ec75ba8df7d7d004536781

You might try to put something like this in /boot/device.hints (or = /boot/loader.conf?):
hint.uart.0.port=3D"0x3F8"
hint.uart.0.flags=3D"0x10"
hint.uart.0.irq=3D"4"
hint.uart.1.port=3D"0x2F8"
hint.uart.1.irq=3D"3"

Ronald.
