It works very well burning audio/data tracks and reading data tracks. I noticed this earlier today with a kernel from Oct 10. The panic with an up to date kernel is different from the Oct 10 kernel. That kernel would usually wait until cdda2wav exited before panic'ing (complaining about dirty pages -- the last 5-10 megs or so of the track would be zero's after reboot), today's kernel panics 8-10 Mbytes into the track (at least the 3 times I tried to read an audio track). stack trace: GDB is free software and you are welcome to distribute copies of it under certain conditions; type "show copying" to see the conditions.
