There's no obvious problem in uart(4). The handling of *.init and
*.lock is all unified in the TTY layer.

Note that the typical scenario for uart(4) to not respect the
baud rate setting is when the UART port is a system device
(i.e. serial console or debug port). Make sure there's no
difference between 8.x and 9.x with respect to which ports
are declared as system ports.
