So it looks > like at least one problem regarding ATAPI has to do with timings. FreeBSD code has had it share of bugs due to spec violation, generally showing up as "timing" problems. One can search the PR for "HITACHI" or "ATAPI" (I can't quite recall what subject I choose) PRs from me. First time, someone found the bug, I incorporated it in my code, sent PR, and distributed the patch to anyone who complained about it (on the lists I read). Then, the code was changed (the whole code), and my PR was closed because it did not apply anymore. Alas, the new code had the same bug. I don't quite recall if I opened a new PR or just sent the patch to (probably) Soren. It was somehow distressing, though, that the new code had the exact same bug as the old, even though it was quite different code. This was ages ago, though. -- Daniel C.
