powerpc: powernowd init script intentionally ignores ppc for loading cpufreq modules

Bug remains in 2.6.24-8-powerpc
Please may we have freq scaling back without having to build our own kernels.

The G5 machines also require their thermal modules built-in the kernel, and not configured as modules. So power management probably does not work on G5 machines either. There was a long saga of past versions of Ubuntu having this *exact* same problem. (Grrr...)

And on certain G5 machines, the lack of power management during install means that the fans run full blast, which to a new user is pretty frightening who doesn't know that the modules get loaded *after* the initial install. On my G5 iMac, this has been the case forever. Without working thermal control, nobody is going to use Ubuntu on these machines that have turned into vacuum-cleaners.

I am not sure if my problem is the same, I have an iBook G4 1.42Ghz. powernowd doesn't start on so I don't have cpufreq. But for me it seems the problem is a init script problem since I can later manually run in terminal:
sudo powernowd
and it works great.
Other than that also therm_adt746x doesn't load automatically on boot, so i need to modprobe it to get fans to work.

This is not a problem of kernel modules being built in but force-loaded by the initramfs scripts.

The powernowd inird script just backs out, assuming the frequency modules to be built in.

I see, thank you Stefan. Somewhat related, but perhaps a new report should be open RE: the thermal modules not being built in. The G5 machines do require thermal modules built in, or power management will not work.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

The powernowd package is obsolete, please do not use it. CPU frequency scaling is now handled by the kernel, so if you still have issues on a modern release, file a bug against the linux package.

This is not an appropriate way to declare a package "obsolete". If you think a package should not be used, file a bug to get it removed from the archive and *then* invalidate the bugs.

There is NO choice for "ondemand" power management (ppc G4) other than user space / powernowd. But thanks for your interest, it's really not that hard to maintain the last powernowd release outside of Ubuntu.

This package is obsolete and has been removed from the archive. Closing associated bugs.
