Bug Description
Binary package hint: linux-image-
Architecture: AMD64 (EM64T)
Kernel Version: 2.6.28-6-generic
linux-image-
Installed: 2.6.28-6.17
Candidate: 2.6.28-6.17
I am using a Conroe C2D (E6750) on an EVGA Nvidia 680i LT reference board, with the latest BIOS update applied. In the BIOS, Speedstep is set to 'Auto' (other option is Disabled), and the processor does report EST capability in its flags. Based on this, I believe I should be able to reduce the CPU speed when system is below full load. However, whenever I attempt to load the acpi-cpufreq module, I get "No such device":
$ sudo modprobe acpi-cpufreq
FATAL: Error inserting acpi_cpufreq (/lib/modules/
Expected Behavior:
acpi-cpufreq loads and is able to adjust the CPU speed with the ondemand (or other) governor.

Why is this a duplicate of bug #355232 ?
Those two bugs are not related to each other!
I also have a EVGA Nvidia 680i LT and exactly the same problem.
It never worked under Linux and this realy sucks!
A total waste of energy!
This bug also appears with Debian lenny and was also true for Ubuntu 8.04
