Thanks. So blkid/mount proves that it's not just a failure in fs detection in the rules, the kernel is not able to talk to the device properly. dmesg is full of errors like
Sep 28 22:24:55 entropod kernel: [ 22.502856] sr 2:0:0:0: [sr0] Sense Key : Illegal Request [current] Sep 28 22:24:55 entropod kernel: [ 22.502859] sr 2:0:0:0: [sr0] Add. Sense: Read of scrambled sector without authentication Sep 28 22:24:55 entropod kernel: [ 22.502863] end_request: I/O error, dev sr0, sector 15694208 Did you try this with a copy-protected movie DVD perhaps? Do you get the same problem with a normal data CD-ROM or CD-RW? I. e. is it specific to the medium or does it happen with any medium? There are also lots of error messages like Sep 30 13:15:22 entropod kernel: [ 506.717387] sr 2:0:0:0: [sr0] Sense Key : Illegal Request [current] Sep 30 13:15:22 entropod kernel: [ 506.717389] sr 2:0:0:0: [sr0] Add. Sense: Logical block address out of range Sep 30 13:15:22 entropod kernel: [ 506.717391] end_request: I/O error, dev sr0, sector 15694328 Sep 30 13:15:22 entropod kernel: [ 506.717393] Buffer I/O error on device sr0, logical block 3923582 Sep 30 13:15:22 entropod kernel: [ 506.717394] Buffer I/O error on device sr0, logical block 3923583 which could be a variant of copy protection, a bug in the CD drive firmware, bad media, or a bug in the kernel; hard to tell for me, this would need input from some kernel specialists. So, let's see on which kind of media this problem occurs in the first place.
