Problem Upgrading to Opensuse 11.4 64bit on my ThinkPadW500

Hello there,
I tried to follow the instructions to upgrade my 11.2 OS to 11.4 from the following link:
SDB:System upgrade - openSUSE
Everything went well except at the restart where the following message pops up:
3.084772 BUG:unable to handle kernel paging request at fffc90405d81ffc and my laptop freezes. I had to change the boot option to splash=0 to start it somehow. Any help to resolve this issue would be much appreciated.
