Bug Description
On my laptop, a Dell latitude CPXj. Using kernel linux-image-
version 2.6.12-7.11 and some earlier versions, i get these messages such as
these in kern.log:

new_state 0 and result 0

And everytime it appears, the computer stops for a second or two, which is very
annoying.
Im guessing this computer is incompatible with the speedstep_smi driver which is
the one loaded.

Could the speedstep_smi driver be blacklisted for this computer model or is
there any other way to fix this?
Please tell me if you need more information.
