Based on a quick look at sata_mv it appears it sets a 64-bit DMA mask unconditionally, but for non-ATA_PROT_DMA commands (which includes all ATAPI), it just falls back to ata_qc_issue_prot which issues via the legacy SFF interface and can only handle 32-bit addressing. So yes, it appears to have a similar bug as sata_nv had.


sata_mv doesn't do ATAPI at all...

Right.. missed that ATA_FLAG_NO_ATAPI. So these issues Tom is reporting are just with a normal SATA hard drive?
