Can you please also try iommu=force? Ah.. strange. There should be no DAC DMA
cycle with the patch applied. The detection went okay but your drive is either
not getting or able to reply the correct data. Can you please test with more
simplistic method? ie. dd a file to the raw device, reboot, dd in the written
file multiple times and see whether the checksum matches the original and if
not whether it changes on each read?
