Hi Jeff,

What are the chances of the SX8 docs being opened? The vendor GPL driver
has bitrotted and the kernel driver offers poor performance or data
corruption. IIRC it's not part of libata but its own block device,
although you were considering porting it to get ATAPI support?

Thanks,

James Andrewartha
