Description of Problem:
My 1200 Mhz processor is detected as a 800 Mhz
Detected 797.471 MHz processor.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Is this a laptop that you booted with power disconnected ?
If so, then yes it was really running at 800 Mhz when this value was determined
No. It was running on AC while I booted. I just rechecked now and it's really
So I checked in the BIOS and after setting the Speedstep config from "Disabled"
to "Automatic" it's now seen as a 1200 Mhz processor. What's up? And did it
really just run at 800 before?
There's some speedstep support in the kernel now...
Works when I set it to automatic in the BIOS.
