Description Peter 2006-08-25 03:05:00 UTC
Most recent kernel where this bug did not occur:
Distribution:Debian 3.1 Sarge
Hardware Environment:Notebook HP Compaq nx9105, Athlon64
Software Environment:GNOME 2
Problem Description:I compiled in all the governors into kernel. I started the
"conservative" because was recommended for my hw platform. I did it by echoing
to /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor... You know.
The governor setting was accepted, however system kept runnung at low frequency
even when I ran 40M package testing with bz2, that loaded CPU for some half a
minute.

When switched to ondemand governor, the power management works (is switching
between high and low freq in depence on load)

I suspected the up_treshold and down_treshold values of governor (in
conservative directory) -they are inverted I feel. AFAIK, the down_treshold
should be IDLE percentage of CPU when it should switch down, and up_treshold
should be IDLE percentage of CPU when it should switch up. However switching the
"down" to 60 and "up" to 20 dosen't help.
