Marc, the same issue is reported in 737388: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/737388
which does happen on the same sata controller: 8086:1c00(pci vid: pci pid) but from 737388, we can find it will work at ahci mode. So I suggest you to enable ahci to fix the issue for your certification purpose. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/794642 Title: [Dell optiplex 390][SFF] Dvd drive not recognized by system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/794642/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
