Hi Markus, Sorry for the confusion, I will clean it up now. It is intermittent and fixes itself if I restart my computer. But it is a consistent problem and at this moment my CD/DVD drive is not working. Below is the log you requested. My computer did not recognize the dmesg.log command but had a lot to say about dmesg. Thanks for looking into this.
