Running Debian SID (installed from the 20190127 CD), this system reports the following: root@lombard:~# sha1sum /dev/sr0 2df40b93c72942e735c1abf62f96a44973244edc /dev/sr0 dmesg reports this when I insert the CD: [ 351.086038] sr 2:0:0:0: [sr0] tag#0 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [ 351.086498] sr 2:0:0:0: [sr0] tag#0 Sense Key : Illegal Request [current] [ 351.086773] sr 2:0:0:0: [sr0] tag#0 Add.
