It appears that disabling HT resolves the issue. I have not had a failure
since.(Knock on Wood)! I think I have now gone longer than the longest
prior lock up. So something in the later Kernel does not like my
processor being in HT mode. I think I will just leave it disabled. I
have to much to do right now to try and chase down the problem. Besides I
am going to move my laptop to 10.2. 10.2 seems to be a much better
release and seems faster.

Thanks to all the responses.
