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,
