  If you are using a laptop it is not recommended to upgrade to Natty due to
the kernel power consumption issues. This is what is gonna happen high temps
and fans spinning like mad. I would drop back to maverick. I personally am
gonna wait til the kernel gets fixed or I can patch it myself. A quick
google search will give you tons of info on the problem with this kernel,
good luck.
