I've not been paying attention to the boot messages on the systems in
some time.

I notice new/adjusted errors and warnings:

ACPI Error: AE_NOT_FOUND, While resolving a named reference package
element - \134_SB_.UBF0.PRT0 (20251212/dspkginit-605)
ACPI Error: AE_NOT_FOUND, While resolving a named reference package
element - \134_SB_.UBF0.PRT1 (20251212/dspkginit-605)

(I expect those 2 are associated with the 2 USB-C ports that FreeBSD is
unable to use.)

ACPI Warning: \134_SB.GPU0._CLS: Return Package is too small - found 1
elements, expected 3 (20251212/nsprepkg-511)
acpi0: Could not update all GPEs: AE_NOT_CONFIGURED

Firmware Warning (ACPI): Possibly buggy BIOS with ACPI_TYPE_INTEGER for
function enumeration
