Bug#638913: linux-source-3.0.0: cpu frequency speedstep_centrino Intel(R) Pentium(R) M processor




It works on my T42 with the 1.8 GHz version of this processor, using
lenny, squeeze and sid kernel versions.  The BIOS version is 3.05a.
Maybe there was a regression in a later BIOS version?

Ben.


I have applied the newest BIOS version available at lenovo support for my T42 (model 2374):
BIOS Version   3.23 (1RETDRWW)
BIOS Date       2007-06-18
Embedded Controller Version 3.03
CPU Type    Intel(R) Pentium(R) M processr,
CPU Speed   1.53GHz

Changing BIOS setting from Slow to Max custom setting changes time between
"Grub loading." to "Welcome to GRUB!" from 15 to 5 cursor blinks :).
However, when system is loaded then mprime benchmark shows exactly the same (SLOW) result regardless of BIOS setting.

System initiation changes the frequency to the lowest one.
Loading patched speedstep-centrino module causes mprime benchmark faster results.
