I'm sorry, forgot to add an important info.
I'm now testing stuff in 6.2-PRERELEASE. I don't know if I did anything that
different but I didn't see this happening in -CURRENT.
I've made a simple test with mpg123. Played a mp3 file really fine without
panicing.. what does artsd do that would cause the panic? Maybe I can't
stress this as much as artsd?
