Hi; While using xen-3.0.2 with 2.6.16.28 kernel CPU (Intel(R) Pentium(R) M processor 1.73GHz) temprature is inreasing up to 104 C (/proc/acpi/thermal_zone/THRM/trip_points reports 105 C is critical for CPU) while idle or no domU working with very low system load, and if i start to use domU, sometimes system freezes or reboots for heat. But the same kernel just without Xen works normally and not causing any heat problem at all (including on high load). Both kernels have ACPI and cpufreq support and according to dmesg output and sysfs values both susbsystems seem works without a problem. What can cause this and how can i debug/solve this issue?

I use PowerNow to dynamically adjust CPU-Frequencies. You have to write your own patch for your Centrino based notebook, and compile the kernel or the kernel Module again. I don''t know if there''s a patch for speedstep-centrino.c available anywhere but it is easy to read the ssource of the powernow-k8 patch an aplly the same to the speedstep-centrino.c file. I attach the really small powernow-k8 patch. -- __________________________________________________ Ralf Schenk fon (02 41) 9 91 21-0 fax (02 41) 9 91 21-59 rs@databay.de Databay AG Hüttenstraße 7 D-52068 Aachen www.databay.de Sitz/Amtsgericht Aachen HRB:8437 USt-IdNr.: DE 210844202 Databay - einfach machen. _________________________________________________ Diese E-Mail und etwa angehängte Dateien enthalten vertrauliche Informationen und sind ausschließlich für den Adressaten bestimmt.

I''ll give a try that patch and if anything changes will report :). Thanks -- S.Çağlar Onur <caglar@pardus.org.tr> http://cekirdek.pardus.org.tr/~caglar/ Linux is like living in a teepee.
