T7200 CPU not detected by est

[Gerrit Kühn]

Hi folks,

I have several systems using T7200 mobile CPUs running under 7-stable.
However, EST does not recognize the cpus. When loading cpufreq I get:

Here is some (hopefully useful :-) excerpt from my dmesg:

When I start powerd with cpufreq loaded like this, the machines
typically crash and reboot. I searched the web for a while to find a
solution for this, but without any success. Does anybody here have some
hints how to get speedstepping & co. to work properly?
