I've solved this problem by downloading the 2.6.7 kernel sources and
modifying the file speedstep-centrino.c. I've changed this:
static const struct cpu_id cpu_id_dothan_a1 = {
.x86_vendor = X86_VENDOR_INTEL,
.x86 = 6,
.x86_model = 13,
.x86_mask = 1,
};
for this:
static const struct cpu_id cpu_id_dothan_a1 = {
.x86_vendor = X86_VENDOR_INTEL,
.x86 = 6,
.x86_model = 13,
.x86_mask = 6,
};
Doesn't using the "acpi" driver with the latest FC2 kernel work? Fedora Core 2 has now reached end of life, and no further updates will be provided by Red Hat. The Fedora legacy project will be producing further kernel updates for security problems only. If this bug has not been fixed in the latest Fedora Core 2 update kernel, please try to reproduce it under Fedora Core 3, and reopen if necessary, changing the product version accordingly. Thank you. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; ca; rv:1.7) Gecko/20040619 Description of problem: On my 1.7Ghz Dothan CPU the speedstep-centrino module detect an unsupported speedstep CPU. I've sended my /proc/cpuinfo at author of the module and he answer me that in the future he would try to resolve it. This is the mail that I've send to his: I'm installed a Fedora Core 2 distribution on my Dell Inspiron 510m laptop and on /sys/system/devices/cpu/cpu0 not appears any file. Because of this it's impossible to throttle the CPU frequence. I'have compiled the latest kernel version, 2.6.7 and it indicates at speedstep-centrino that send to you a copy of my cpuinfo because it's unsupported. This is my "cpuinfo": processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 13 model name : Intel(R) Pentium(R) M processor 1.70GHz stepping : 6 cpu MHz : 1698.751 cache size : 64 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr mce cx8 sep mtrr pge mca cmov pat clflush dts acpi mmx fxsr sse sse2 ss tm pbe tm2 est bogomips : 3375.10 Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Load the module speedstep-centrino or, if it's compiled into de kernel see the kernel messages. 2.Appear that there found an unsupported speedstep CPU. 3.Doesn't appear any file on /sys/system/devices/cpu/cpu0. Actual Results: Doesn't appear files on /sys/system/devices/cpu/cpu0 and it's impossible to throttle the CPU frequency. Expected Results: Files would appear into that directory to access the cpu speedstep properties. Additional info:
