Seems to be the same problem. You can force PIO mode by adding your
device's ID to ata_dma_list[] in libata-core.c. It will force PIO mode
on all controllers, though. Proper way would be to implement
ops->filter_mode() in sata_via.c and force PIO for ATAPI devices, but
I'm not sure whether the 'force PIO' approach is the correct one.
