DBS: CONFIG_X86_SPEEDSTEP_CENTRINO=m on 2.6.9-1.860 x86_64 kernel

Description of problem: $subject. It should be =y (as it is for x86). Version-Release number of selected component (if applicable): 2.6.9-1.860
I'm closing this bug as we've agreed for GA to disable the speedstep centrino driver. We'll use 138952, to track the progress of this feature in U1, since it has all of the history already.
Duh, right, I agree it should be disabled, not =y, my mistake. Can we leave this open, mark MODIFIED when the change is committed to CVS?
right, two changes needed to be made from rc1: 1) disable CENTRINO on x86_64, captured now in this bug 2) enable ACPI_CPUFREQ=y on x86_64, per bz #142152 This should now be committed, but i'll let Dave move it to modified.
been thinking about this situation. I think building ACPI in is going to break every other cpufreq driver, as cpufreq only supports 1 driver right now, and acpi is going to claim success on a majority of hardware, including hardware that for eg, may be better suited with powernow drivers or such. This might be fixable just by adjusting the link order.
The acpi driver will load after everything except p4_clockmod as it is currently built based on load order, assuming all the other drivers are built-in, and it looks like it's "first one that works wins".
yes, that'll teach me to check the code before making comments. :-) p4-clockmod isn't too useful anyway, so the current status seems fine.
2.6.9-1.871_EL has the following: kernel-2.6.9-i686.config:# CONFIG_X86_SPEEDSTEP_CENTRINO is not set kernel-2.6.9-i686-hugemem.config:# CONFIG_X86_SPEEDSTEP_CENTRINO is not set kernel-2.6.9-i686-smp.config:# CONFIG_X86_SPEEDSTEP_CENTRINO is not set kernel-2.6.9-x86_64.config:# CONFIG_X86_SPEEDSTEP_CENTRINO is not set kernel-2.6.9-x86_64-smp.config:# CONFIG_X86_SPEEDSTEP_CENTRINO is not set kernel-2.6.9-i686.config:CONFIG_X86_ACPI_CPUFREQ=y kernel-2.6.9-i686-hugemem.config:CONFIG_X86_ACPI_CPUFREQ=y kernel-2.6.9-i686-smp.config:CONFIG_X86_ACPI_CPUFREQ=y kernel-2.6.9-x86_64.config:CONFIG_X86_ACPI_CPUFREQ=y kernel-2.6.9-x86_64-smp.config:CONFIG_X86_ACPI_CPUFREQ=y So, that's what's mentioned in comment 5 and since this kernel is included in our latest trees, closing out.
