AFAICT, the mlx4 driver is correctly doing pci_set_dma_mask(pdev, DMA_BIT_MASK(64)); pci_set_consistent_dma_mask(pdev, DMA_BIT_MASK(64)); during init, but the BUG being hit here is: BUG_ON(addr_width < BITS_PER_LONG && (iov_pfn + nr_pages - 1) >> addr_width); Any suggestions on what might be going wrong here?
