I either understand but also don't understand the discussion about this bug and it's consequences here. But this is a serious bug for some people. For a non experienced user, this kernel leads to an unusable system. A (slightly) experienced user will try to start the system with the previous kernel. Minimum a workaround like this should be mentioned here: Go to YaST, start boatloader module and set default kernel to previous (Boot Loader Settings - Default Boot Section). So it's possible to "sit out" the problem until the next kernel is provided in the update stream. That's why I putted myself to the CC list... ;-)
