Did you try some stress-testing of the controller?

I don't know what your hardware setup looks like. I had some problems
with extra bytes when a DMA transfer failed and buffers were not
properly flushed on my SPI controller or the DMA transfer was just
programmed incorrectly. Not sure about the exact cause yet.
