It appears that scsi-emu is not effected by this memory leak when writing audio cds. So it would appear that ide-cd along with any of the dependent ide source files is the culprit. But I cannot find anywhere in ide-cd that is apparent to being a mem leak. There are various conditions in ide_do_drive_cmd that state that the cdrom driver has to be very careful about handling but without intimate knowledge of the driver, I can't be sure that it's sufficiently handling those situations. Surprisingly, it's very hard to find anyone who's used the native atapi mode to write an audio cd in 2.6. Which is partly why this problem hasn't generated more mail traffic here I would guess.
