[Bug 45764] cpufreq does not seem to work on G4 TiBook 667MHz

[Heikki Lindholm]

Public bug reported:

On Dapper "current" (060520):

dmesg says:
Low: 667 Mhz, High: 667 Mhz, Boot: 667 Mhz
sysfs agrees:
> cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq
667000
and the PowerBook fan agrees, too, and consequently stays on after maybe half an hour of minimal usage. I'm quite confident I was using Debian sarge (or pre-sarge testing) on this machine some time ago with no problems like this.

Also, cpufreq modules are loaded and powernowd is running.


Note: the original reporter indicated the bug was in package 'linux-image-2.6.15-20-powerpc'; however, that package was not published in Ubuntu.

         Status: Unconfirmed
