I've tried that too. I just stepped through most of the
console_initcall sequence with gdb and it seems like everything is
getting set up properly, including irq and mmio settings for the
serial devices, but still nothing gets printed. Maybe interrupts
aren't getting routed?

I just discovered the udbg-immortal command line option, which
prevents console_init from optimistically disabling the udbg console.
Debugging this problem should be a lot easier now that I can see
console output past console_init.
