Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.8 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

Few forums suggested that upgrade to kernel 4.7 fixes some of the issues so I though to give it a try. Firs of all I tried to update my laptop and everything went well. Performance also improved and slow shutdown and issues of freezing during shut down also seems to haven't occurred atleast until now. Later decided to upgrade the kernel on my main work computer as well. Here again I see improvement in behaviour of my computer but problem is I see some errors on the boot screen. I have also attached a screen shot, please check. Never noticed this issue with previous versions of Linux Mint or after upgrading kernel in the past. Seemed like issue with CD/DVD drive. I took out the disk out of the DVD drive and error screen seemed to be vanished. I inserted a blank CD in the drive and error reappeared but number of error lines reduced. I want to keep the disk in the drive which I always had in the past without any issue. Please look into the issue.
