> It sounds like a hardware fault. Could well be I guess.
However, whilst booted I just whacked the DVD drive in and am now listening to a CD on it fine. So it certainly works. Also, this issue only started once I starting using 20.04. It never happened with 18.04. These facts would seem to suggest a software issue to me. But yeah, for now I'm mostly just leaving the drive out so that booting up works! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1877388 Title: If DVD drive is present system very often fails to start-up To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1877388/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
