Can you add CPUFREQ_ENABLED="no" in /etc/sysconfig/powersave/cpufreq and try some things manually, pls. This doesn't work. I had to manually comment out the loading of speedstep-centrino etc in /etc/init.d/acpid (lines 180 and 181)
First, is this phenomenon always happening or does it only happen after some time? It happens every time
Try to load the cpufreq driver by hand (modprobe speedstep‑centrino, if this does not work it should be modprobe acpi). After modprobe, CPU freq. is on 100%
Load governors by hand: modprobe userspace;modprobe ondemand;modprobe performance mblxws01:/home/mboman # modprobe userspace;modprobe ondemand;modprobe performance FATAL: Module userspace not found. FATAL: Module ondemand not found. FATAL: Module performance not found.
cd /sys/devices/system/cpu/cpu0/cpufreq echo ondemand >scaling_governor (does cpu get switched up and down on CPU load?) Yes, CPU is switched up and down
Let it stay down and try: echo performance >scaling_governor Is the machine on lowest freq now? If yes, we hit the bug. No, CPU freq goes to 100% and stays there
Does echo userspace >scaling_govornor;echo 2266000 >scaling_setspeed switch up to highest freq now? CPU is already on max freq. echo'ing 800000 will set it to min freq. Then I can switch it back to max with echo'ing 2266000
If yes, do echo ondemand >scaling_governor (does cpu get switched up and down?) Setting it to ondemand makes it switch up and down
It seems that if I make one manual change to the governor, it will behave as it should. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
