I tried installing Ubuntu Hardy (Kernel 2.6.24) and expirienced the same problems as I did using Suse. So this is not a Suse specific problem. It really seems to me that it is a kernel problem as described by you on lkml, the behavior of my notebook is exactly the same. I started Suse and before starting KDE I went to tty1 and did a cpufreq-info. Then I waitet for some time, and did it again and again. scaling_max_freq was 2GHz the first time (should be 2.5), then 1.2GHz and finally 0.8GHz. That happend within 3 minutes. And now I can not get it back up again, no matter which power-govenor I use. And deinstalling lm_sensors did not help (and it never was installed under Ubuntu and I still have those problems) This really drives me nuts, I mean what's the point in having a 2.5GHz cpu if you can only use 0.8GHz? Is there anything I can do to help solving this problem?
