Curiously the other cdrom commands work correctly. } I also get this error with a -stable kernel. Well, the message is quite clear: The CDROMs don't support the command they receive, Don't know, whether the Adaptec implements special magic to better deal with that situation, but it is no driver problem. (Which Adaptec did you use successfully before ?) The driver sent the command, received the status and let the GENERIC SCSI code write that message ... Perhaps it is possible to find out, WHICH field has been the cause of the command failure. But I guess this will require some CDROM technical manuals, that I don't have access to.
