[Bug 223361] Re: Powernowd does not scale my C2D E6550 higher, even with 100% load

[jstammi]

I can confirm this for Karmic x64 using Phenom X4 925 on GA-MA78G-DS3H.

I upgraded my system to this configuration and wondered the cpu
frequency stays for 800Mhz while running prime95 with 4 load threads.

Stopping powernowd immediately raised frequencies to 2800Mhz (as
expected). Starting again lowered frequencies to 800Mhz again.

Though the 4 power levels are detected afais correctly:
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
2800000 2100000 1600000 800000

And for short time periods one can see the cpu frequencies on single cpu
increases to 2800Mhz, too. But with prime95 running I would expect
highest frequency all the time.

Searching available packages a bit I found the package powersaved to
replace powernowd. After installation of this cpu frequencies now behave
as expected.

I'm not sure if the powernowd was installed by default - it might have
happened that it was installed on my request (while looking for hardware
sensors support).
