Hi
just while ATAPI + ide-scsi and cd drive are on topic here might i also add that this bug has always been very easy for me to trigger in the 2.4.x series i have never been able todo it in 2.2.x though.
its very easy as in insert slightly scratched cd and do dd if=/dev/scd1 of=/dev/null bs=8192k wait until it gets to damage part of the disk and then the following arrives.
i belive i have read some posts that this has been seem from other people with bad media in dvd drives as well.
