Sometimes DMA mode crashes the PI. I have some theories on what is happening:

Out of bounds write: The DMA controller writes outside the GPIO memory area
Out of bounds read: The DMA controller reading from an invalid address might potentially crash the CPU
Bad setup of cyclic DMA chain: There might be something wrong with the DMA controller control blocks
