Bug#470474: cpufrequtils: Laptop limited to 1.2GHz vs 2.2GHz when no battery, running on AC only.



Okay, I can't get reportbug to work properly at the moment, it fails to
reach BTS for linux-2.6


In any case, here is the details I have now:

Package: linux-2.6
Version: 2.6.32+25
Severity: normal

Running linux-image-2.6.32-3-686-bigmem 2.6.32-9, this problem is better
without a battery in the battery slot, giving me 1.6GHz.

Problems though, is that now the machine is preferring 1.6GHz now for
everything, no matter what power profile I give it. No matter what I try
to force. Sometimes it even locks at 800MHz. I can see the policy change for
a few milliseconds, but goes right back to 1.6GHz

Plus the 2.6.32 kernel screws up the X rendering and makes it feel like 
I'm back in 1994 running CDE on OSF/1 box, using XDMCP. Lethargic response
times, likely due to the GEM system changes.

I've switched back to linux-image-2.6.31-rc4-686-bigmem 
2.6.31~rc4-1~experimental.1~snapshot.14067 as my kernel in use. This gives
*MUCH* *MUCH* better CPU speed results *AND* the X renders fast and light, 
like it should. Since the updates to cpufreq* packages (and other things I am sure)
I am running at 2.2GHz all the time (without the battery in, or out ON AC only)

This kernel was installed from the Debian Kernel Builder site back when I was having
huge issues with the earlier kernels and X rendering and everything now seems to 
work with it and the updated packages for squeeze.

Someone needs to go look at that 2.6.31 kernel and figure out why it works so well, 
va the cruddy way the "current" one works.
