Hello, These scaling problems are plaguing me on my Thinkpad T43 as well. The behaviour is very difficult to predict; sometimes it will scale fine on AC and battery power after a fresh boot, then begin to have problems on battery. Now it is failing to scale at all, even on AC power, on fresh boot.
My exact model is a 2668WMY, with a single core processor. (CPU details below) I've also given the 2.6.32-22 phc kernel a try, and while it appeared to be helping at first, I'm now back to the unpredictable behaviour. I compiled and loaded the phc-intel module, and whlie I can now make the voltage adjustments, there's no help on the CPU scaling front. processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 13 model name : Intel(R) Pentium(R) M processor 2.00GHz stepping : 8 cpu MHz : 800.000 -- ThinkPad T43 CPU scaling (ondemand/fixed/..) not working correctly - Ubuntu 9.10/10.4 (stock & mainline) https://bugs.launchpad.net/bugs/519142 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
