Well, seems I can't delete the post... that's embarrassing. Also, It won't let me post what I actually want to (or edit this with what I actually want to).
 
So I'll just link to my stackoverflow question and hope that works...

The problem may not be in the DMA, but in the system frequency setting and/or UART setting.
You have enabled RXIE in the UART setting, but there is no interrupt service for it.
First you need to make sure that the system frequency and U1BRG valie is correct.
