Does the same thing happen with a cleanall ? There's an open bug about the checksuming of those SRC_URI elements, and you are likely hitting it if there's no cleansstate or cleanall happening. Also, you've confirmed that CONFIG_IO_DELAY_0XED isn't missing any config options that it has as dependencies ?
