Confirmation of "the bug is back".
I run Ubuntu 12.04 with the latest
linux-image-powerpc64-smp_3.2.0.25.27_powerpc.deb
kernel and the fans are running nuts.
Please anybody fix this bug, because there are still people out there who like
to keep iMacs running
under Linux instead of the outdated
I just tried the daily builds from Ubuntu 12.04 and while launching the
install process the fans starts to spin very, very fast.
I guess this bug came back.

For this specific computer, you should be fine for future upgrades

Those errors can be ingored. They just mean a few modules didn't match
your hardware type. Since the list put into /etc/modules won't include
them, you won't see those errors at boot time.

Try the commands again after doing:

That will get you logged in as root, and from there you'll have the
permissions you need to update the /etc/modules file. (In your command

OK. I understand there can be problems with using "apt-get dist-upgrade"
to upgrade from Dapper to Edgy. If I am only able to get a Dapper CD to
validate, is there a way I can just upgrade the kernel to Edgy until the
kinks in the "full" upgrade get ironed out?

"powernowd" is the cpu-frequency management tool, and probably isn't
needed for the fan control, but it's handy especially for laptops. The
windfarm modules are only available with the new Edgy kernel.

We had the installer manually adding these modules to /etc/modules. Not
sure why it doesn't anymore.
The magic for the modules to be autoloaded by udev isn't going to be
supported until feisty's kernel.

To make these module load on bootup, I also did this as root:

A better fix is for udev or similiar to notice the hardware and take the
right actions.

Ah nevermind. On a stock Edgy install, this seems to have solved the
problems:
# As root, type:
apt-get install powernowd
cd /lib/modules/$(uname -r)/kernel/drivers/macintosh
ls | cut -d. -f1 | xargs -n1 modprobe
Seems that what's missing in Edgy is the correct knowledge to load the
right module
If anyone has solved the fan issue by compiling with "g5_defconfig", can
you attach your "dmesg" output from bootup? From looking at the
differences between the stock Ubuntu kernel config and the one generated
with g5_defconfig, it's not obvious what the critical differences are.
Thanks!

Hi!
I am using a iMac G5 (first version) 1.8 GHz, I have just tried edgy

The kernel supports the fan control since version 2.6.15 or 2.6.16. The
