stm32f3discovery: USART2 interrupt handler looping

Hi, I tried to set up some code for handling data received on the USART2 peripheral but for some reason it seems to read one byte and then keep re-entering the interrupt handler without setting the RXNE interrupt flag (or any other interrupt flag, I checked that too...). Here is what the relevant code looks like:

. I removed checks for all the other possible non-error interrupt flags since it they weren't being triggered.

Looks reasonable enough, I'd probably initialize the NVIC first.

How are you testing it?
