A few questions:

1) What does "accidentally works" mean?

2) Do I understand you correctly: 6300ESB works on FreeBSD 5.5 and 6.2,
"accidentally works" on 6.3, but does not work on 7.0?

3) Have you tried 7.1-PRERELEASE?  I make no promises, but additional
confirmation would be helpful.

4) Have you contacted the ata(4) author, Soren Schmidt <sos at freebsd.org>
about this driver regression?

5) Is there a PR open on this matter, or have you filed one?
