Well, I still have the same problem, but at least I have a good workaround (taken from https://bugzilla.redhat.com/show_bug.cgi?id=504041):
$ sudo umount /dev/sr0 $ sudo rmmod pata_via $ sudo modprobe pata_via After running the above three commands, Ubuntu recognizes the CD/DVD again. It seems to be a problem in the PATA driver for VIA chipsets. Does anybody with the same symptoms have any chipset other than VIA? ** Bug watch added: Red Hat Bugzilla #504041 https://bugzilla.redhat.com/show_bug.cgi?id=504041 -- Kernel doesn't detect media in CD/DVD drives https://bugs.launchpad.net/bugs/544548 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
