Just compiled 2.6.8.1 and tested audio extraction. The bug is there.
After that, reran the test with 2.6.7. Everything went fine. So it must have
been between 2.6.7 and 2.6.8.1 when the bug got introduced. Any additional
debugging options in the ATA/IDE cd driver i could turn on so that I could
get more verbose messages while executing cdda2wav?
