Check your boot sectors. boot0 is shared between the slices, so
that’s less of a concern, but boot2 is specific to each slice.
You can force a serial console by writing “-P“ to /boot.config
(if not already done).
It helps if you tell the kernel specifically to use a serial
console (as well):
boot_serial=yes
hw.uart.console=“io:0x3f8”
boot_multicons=yes
I have found that with vt(4) it’s pretty much impossible to
not have it claim the console. I haven’t figured out why...
