From the log and looking in to dts, the drivers seems to the one for "marvell,armada-370-neta". Issue looks the data from the dma has gone bad and subsequently referring the wrong data has resulted in the crash. Looks like the dma_masks is the one going wrong. Can i get some logs from mvneta_probe, about dev->dma_mask, dev->coherent_dma_mask and dev->dma_ops with and without the patch to see whats the difference ?
