I made a diff from booting 13.1 and 14.2 with boot_verbose, and this stands out:
(only in the 13.1)

-pcib0: allocated type 4 (0x3f8-0x3f8) for rid 0 of uart0
-pcib0: allocated type 4 (0x3f8-0x3f8) for rid 0 of uart0
-uart0: <16550 or compatible> at port 0x3f8 irq 4 flags 0x10 on isa0
-pcib0: allocated type 4 (0x3f8-0x3f8) for rid 0 of uart0
-uart0: console (115200,n,8,1)
-ioapic0: routing intpin 4 (ISA IRQ 4) to lapic 2 vector 53
-uart0: fast interrupt
-uart0: PPS capture mode: DCD
-pcib0: allocated type 4 (0x2f8-0x2f8) for rid 0 of uart1
-pcib0: allocated type 4 (0x2f8-0x2f8) for rid 0 of uart1
-uart1: <16550 or compatible> at port 0x2f8 irq 3 on isa0
-pcib0: allocated type 4 (0x2f8-0x2f8) for rid 0 of uart1
-ioapic0: routing intpin 3 (ISA IRQ 3) to lapic 3 vector 53
-uart1: fast interrupt
-uart1: PPS capture mode: DCD

does this help?
cheers,

Hi,

A change was made that uart does not attach on isa anymore.
I think this was the commit about it:
https://cgit.freebsd.org/src/commit/?h=releng/14.2&id=74b9fc7adcf4afb1c3039267e338c3cfdf022957

I don't know much about the details. Somebody else can tell more.

Regards,
Ronald.
