jrohwer Posted March 27, 2008 Report Share Posted March 27, 2008 When I suspend to ram (either using kpowersave, or typing "pm-suspend") at the command line and start up my laptop again, cpufreq stops working. I have traced this back to the fact that the symlink /sys/devices/system/cpu/cpu1/cpufreq -> /sys/devices/system/cpu/cpu0/cpufreq which links the cpufreq settings for the 2 processors, has disappeared after the resume. I also cannot create this symlink by hand (I must admit that I have very little knowledge of how sysfs works). I can still manually change the cpufreq settings for cpu0 with e.g. # echo "performance" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor and it affects the clock frequency of cpu0, but for cpu1 it is disabled, and it also doesn't work with kpowersave (presumably because it can't access cpu1). Has anyone experienced similar things or got a fix for this? System: Dell Latitude D630 with Intel Core2Duo T7300 processor OS: Mandriva 2008.0 x86_64 architecture Quote Link to comment Share on other sites More sharing options...
coverup Posted March 27, 2008 Report Share Posted March 27, 2008 Welome to the forum. I have checked my laptop (ThinkPad), and the link is there. I run Mandriva 2008.0, i586 version. Quote Link to comment Share on other sites More sharing options...
