VFS: Cannot open root device "null"...

Yesterday after the HTC Magic upgrade we successfully used a DVD-RW with openSUSE 12.2 to restore openSUSE functionality to our main desktop system. We even used the DHCP 4 or 6 option to connect successfully to our local area network and the internet, and the internet connection worked both in Gnome and KDE. After this success we today attempted to use the same DVD to upgrade our notebook and receive the following error message as the linux kernet was loadning "VFS: Cannot open root device "null" or unknown block(0,0): error -6". Googling this errror message we discovered, that the cause could be a bad DVD or CD. This was not a big surprise since we tried the DVD in both the build in drive on the Lenovo E520 and a USB attached drive with the same results.
Currently we are downloading a new iso-image, and will report on progress with the upgrade later. The direct download of the DVD iso latest a little less than one hour after which it was burned to a new DVD+RW. From this openSUSE 12.2 was successfully installed on the Lenovo E520. During the install the wireless connection was activated, and we for the first time was able to apply the patches before the final hardware configuration. Also on the Lenovo internet connection worked in both KDE and Gnome. However, we are not using the Network Manager at this time.

PS: KDE was a new learning experience for us. Have been mostly working in  Gnome, and getting a bit frustrated with the new icon less desktop.
