sr0 error on boot screen

[Jack]

Hello

I had performance relate disuses on fresh install of Linux Mint 18, especially my computers were getting stuck during shut down. 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.

Specifications of the computer:

Linux Mint 18
Kernel 4.7
AMD 8350
Asus M5A97
24 GB RAM
Nvidia 780ti
Asus Xonar D2X soundcard
WD Green 500GB HDD
Asus DVD writer

Thanks and regards
