I haven't seen anyone work on the recent SB600 errata, where the
hardware does not like 256-length PRD entries.
Is this correct, AMD folks?
It hurts performance on SB600, but it is more important to get a
correct patch eliminating the data corruption/lockups, and then later
on tune for performance.
We simply limit each command to a maximum of 255 sectors, on SB600.
