During initialisation i get the following message: speedstep-centrino: found unsupported CPU with Enhanced SpeedStep: send /proc/cpuinfo to Jeremy Fitzhardinge What I did. As i received no feedback I look inside the cpufreq sourcecode that throw the error and I tried to fixed it myself. I compared it with the content of my /proc/cpuinfo: cpu family : 6 model : 13 model name : Intel(R) Pentium(R) M processor 1.50GHz stepping : 6 cpu MHz : 1500.834 cache size : 64 KB I located a correct cpu_id cpu_id_dothan_b0 but I wasn't able to locate were is it used (it seems to differ from the banias code). In addition in the centrino_cpu_init_table(struct cpufreq_policy *policy), the loop that detect the processor failed as my processor string contains 1.50Ghz and not 1500Mhz (maybe an issue related to my Asus BIOS). In fact, I could try to make a patch for making my processor accepted by the centrino checking code, but after this I ignore what will happend as no predefined tables frequency/voltage exists like with the Banias. Will it burn my computer :) or will it nicely use acpi/ich4 in some way ? Cheers, Damien Marchal.
