I had the same problem. I ended-up 'fixing' it by replacing my DVD cable (40-pin) with an 80-pin cable.
It could have problem detecting/using ATA33 mode. In my case, changing the cable let the driver run properly in ATA66 mode (bug#275335). -- 8.10 alpha4 / Kernel gives I/O error on CD(?) https://bugs.launchpad.net/bugs/259901 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
