odd, we never loaded speedstep-centrino on any est capable machine only based on the kernel version since (almost) forever, see: http://git.kamineko.org/cgi-bin/gitweb.cgi?p=cpufrequtils.git;a=commitdiff;h=8c4880e717bf3fec4034ec2cfed346550eb1a213 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=502431 To be honest I think it should be the Ubuntu package that should get code from Debian. > load the e_powersaver module on VIA CPUs with the est flag (perhaps > this is the solution for #566214?). e_powersaver won't load anyway on non-est capable cpus, from e_powersaver.c: if (!cpu_has(c, X86_FEATURE_EST)) return -ENODEV; and really, looking at the help text from the kernel sources it looks like acpi_cpufreq should be used instead: help This adds the CPUFreq driver for VIA C7 processors. However, this driver does not have any safeguards to prevent operating the CPU out of spec and is thus considered dangerous. Please use the regular ACPI cpufreq driver, enabled by CONFIG_X86_ACPI_CPUFREQ. I would rather do that at this point. -- mattia :wq! -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected]
