I was wondering if there was a way for the cdrom module to know when the media gets changed so that the flag can be cleared and only reset if we can do multi-frame DMA with the new media? I have been digging through the code but can't see an obvious place where this happens, pointers and other comments welcome. Currently I've got 2.6.7-rc3 patched, would you accept or you want me to check it goes cleanly into the latest and greatest? Cheers, Nige
