I was experiencing similar problems (same "drive not ready for command" error, and the dvd drive would immediately close whenever I tried to open it, like in https://bugs.launchpad.net/ubuntu/+bug/98806). These problems were not fixed by disabling the cdrom and ide_cd modules. I was also receiving the following message several times per second:
device-mapper: ioctl: unable to remove open device sda6 sda6 does not exist on my system, and never has. I also noticed (in top) that the an evms process, and udevd were popping up repeatedly (presumable polling something). I took a hint from http://kristof.willen.be/?q=node/762, and removed the evms and evms- ncurses packages, and the problem was solved. -- Feisty freeze, kernel (?) tries to access DVD drive https://bugs.launchpad.net/bugs/75295 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
