I observed it working in 1 in 10 or 15 boots. Seems to occur after disabled the early console and moving over to ttyS0. I was unable to get debug out of the kernel at that point no matter what kind of kernel console overrides I tried.

For debugging i think it is best to use something like:

console=ttySIF0,115200 earlycon=sbi

note that by default kernel/systemd seem to enable sbi0 hvc0 (via sbi) ttySIF0 consoles all of which seem to be the same thing.

It is quite confusing.
