Yes yes I did use this command line parameter. So the fact that my system only shows C1 is normal in this case I suppose. I will try to boot the system without the processor.max_cstate=1 parameter. > Also a wiki page about this processor tells that the new "mobile" (only > AthlonXP "M") feature is to support Powernow!. So it really might have to do > with tsc+powernow!. Powernow does not work on my system. ---------------------------------------------------------------------------- [ 121.157837] Fast TSC calibration using PIT [ 121.170872] powernow: Trying ACPI perflib [ 121.170930] powernow: ACPI perflib can not be used on this platform [ 121.170973] powernow: ACPI and legacy methods failed ----------------------------------------------------------------------------- I bought the XP-M on Ebay. My mainboard (a FX41 from Shuttle) was not supposed to run mobile Athlon so I think the BIOS does not support the XP-M. I will try patches from http://www.yggdrasl.demon.co.uk/code/ but I need to guess the correct parameters to manually configure Powernow on my Athlon. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
