Oh, almost forgot, don't remove cpufrequtils. These application are responsible to prolong your battery charge by downclocking (thus preserve electricity) within processor. Normally you have an "ondemand" setting which may throttle processing power up and down.

I think Anthony and Brian hit upon the solution. At least since doing 
the changes they suggest, I have not had any lock-ups. But we'll see. 
It's only been a couple of days.
Thanks!
