Spent all weekend tracking down a bug in the display driver I wrote. It was causing my radio transceiver to go wonky (they share an SPI bus), but only when writing to the display with DMA!
Long story short, it ended up being a few bytes remaining in the RX buffer after the DMA transfer, which the radio driver would read when it was its turn with the bus. A single line of code and I am immensely satisfied right now
