Some wild guesses: 1. Since this happens while enumerating USB devices it could be a power supply issue. I have seen boards work fine until the voltage dips as a result of USB devices getting turned on. 2. This reminds me of how the mx51 kernel was behaving when u-boot was enabling the watchdog timer but the kernel was not disabling or updating it.
