Perhaps the system was looking for resume space on sr0? It seems a strange thing to do. But also it is quite a coincidence if the errors occur when the resume space is messed up, and they go away when it is fixed. That has happened twice. It might be a good way for someone to reproduce the error on some other machine. I have no problems with the CD/DVD writer and have used it a few times recently.

This time I knew what I had done, I commented out a line in fstab referencing a swap space, because the system had two swap spaces defined and I wanted to use one for something else. What I overlooked was that this swap space was also the resume space. During the boot there were other messages which did not appear in the journal so I filmed them with a smart phone: Running /scripts/local-block.. These occurred over and over, but allowed me to find this site: https://tipstricks.itmatrix.eu/solving-the-running-scripts-local-block-loop-while-booting-in-linux/ Which explained the problem and how to fix it. I had already edited: /etc/initramfs-tools/conf.d/resume To use the other swap space. But this did not help because I missed this crucial step: sudo update-initramfs -u After I did this, the errors went away. I don't know why the errors reference sr0, it's a mystery.
