[Bug 519142] Re: ThinkPad T43 CPU scaling (ondemand/fixed/..) not working correctly - Ubuntu 9.10/10.4 (stock & mainline)

[plafond]

I can also confirm the bug.

Thanks sotirovlyu for the suggestion - installing current version of
linux-phc (2.6.32-25) seems to have (partly) resolved the issue for me
as well.  I simply installed from ppa and rebooted.   This allows me to
now run at max frequency however there are still some issues with
scaling.

*************************************************
NOTE - i've observed the following behaviour after making the changes ilsted above:

when i plug in the power, regardless of what the 'governor' value is
set, the MIN and MAX frequency values both get set to my MAX frequency
(1.87GHz)

when i unplug the power, regardless of what the 'governor' value is set, the MIN and MAX frequency values both get set to my MIN frequency (800MHz)
***********************************************

I think this could be an indicator of where the original issue actually
lies.  Anybody else notice the same thing?

If the module which sets the scaling is always applying the 'case2'
(mentioned above), then the original bug reported would be partly
replicated.  Prior to installing linux-phc module, the MIN/MAX frequency
was always set to 800MHz, even when I manually changed the governor to
'performance'.
