/dev/sr0 is your CD/DVD drive, so that's not an essential problem.

It means that some sectors on the disc were not readable, which could
be due to a bad disc. Or you may need to dust off the drive.
I've seen this message several times myself when I forgot to remove a CD
or DVD before powering off the machine. On next boot it is then spun up
when udev starts.
