Careful. It may be that your fix just avoids the corruption because the
other changes make it ok - like the 16-sector multi-count thing maybe
hides a problem that might still exist - it just changes the "normal"
timing so that you won't ever see it in practice any more.
These kinds of magic interactions is why I'm not at all happy about driver
changes until people really know what it was that caused it, and _know_
that it's gone.
Anyway, for you the problem apparently happened even on a 686a, but just
the 586 series. Correct?
