Yeah, sorry about that.

I'm surprised because I would expect to see the message "missing or
empty /vdevice node" here. I guess it's possible there's still a
problem here; my test system finally came back so I'll check it out.

You might try the kernel parameter "initcall_debug" to print addresses
of functions being called at that stage of boot (see do_initcalls in
init/main.c). Then refer to System.map, although I think since we tend
to have embedded sysmap these days that printk could be a bit more
useful...
