After running the updates from Friday around 3pm, I seem to be crashing on bootup. Everything looks fine until it gets to clvmd. It fails to load, which is no big deal but then it goes to a black screen. It stays on this black screen for a minute or two and then I hit CTRL-ALT-Delete. It will bring me back to the Services screen and says "NFS lockup:      [Failed]." It then sits there for about 30 seconds and goes back to the black screen. I give it a few minuts and then hit CTRL-ALT-Delete again and it doesn't do anything. I have to manually shut down the computer. I have tried previous kernels.
 
I can log into WinXP fine, so I guessing it isn't a hardware failure, which was my first thought.
