You may want to use udbg_printf() to track down what's up. There's some fishy code there indeed, what happens is that the legacy serial code creates a platform device at boot time. Then, the of_serial attaches to the device node for the same device and tries to register it. It's supposed to "detect" that it's the same device but yeah, it may be buggy, I've seen problems with it in the past, among others, I think it can lose some state. In the meantime, removing SERIAL_OF_PLATFORM is a good solution.
