Perhaps the > new drivers in 8.0 will fix these problems? I haven't seen original chip errata to be sure, but ata(4) driver now includes some workarounds for this chip.

It is already possible in HEAD to write quirks for specific device models and firmware revisions. Also to control NCQ usage. -- Alexander Motin
