I am new to the list and to Linux. I am trying to find a distro that my G5 doesn't have a revving fan problem with. Here is info on my hardware:
I started out with YDL 4.0 on my PowerMac G5 Dual Processor 2.0GHz machine and there were no problems with the fans.
Later I got some 2.5GHz models and 4.0 and 4.0.1 and the fans were blaring because of a simple check needed for PowerMac7,2 versus PowerMac7,3. I swtiched to FC4 at this point and that fixed my fan problems...sort of. At this point I have some 2.7GHz machines that are prematurely panicing about overheating, There is a fix for this in 2.6.15 for which there is a FC4 updates testing kernel. However, as I just reported to the fedora-test-list, for some reason the driver doesn't seem to be initialized I'm back to full blaring fans on those machines for a while.
One problem I had with FC4 is that I couldn't get it to clean install on the new machines because of a disk druid problem or something like that. So I actually installed YDL all the way through the first reboot, then I turned around and installed FC4. if I tried to reboot just after the partion part and not after actual package installation it didn't work, I think it wasn't flushing the right stuff to disk until the end. I just did minimial packge installs to get through it quick.
Now, you have a different model that I have not tried. searching through my collection of recent FC4 updates and updates-testing kernels (which I happen to have around because of my own 2.7 GHz problem investigation) I see that the new windfarm driver is specifically for the PowerMac9,1:
mchammer:~/kernel $ grep 9,1 */*/drivers/macintosh/*.* 1823/linux-2.6.15/drivers/macintosh/windfarm_pm91.c: * PowerMac9,1 1823/linux-2.6.15/drivers/macintosh/windfarm_pm91.c: if (machine_is_compatible("PowerMac9,1")) 1823/linux-2.6.15/drivers/macintosh/ windfarm_pm91.c:MODULE_DESCRIPTION("Thermal control logic for PowerMac9,1"); 1823/linux-2.6.15/drivers/macintosh/windfarm_smu_sensors.c: /* Try to use quadratic transforms on PowerMac8,1 and 9,1 for now, 1823/linux-2.6.15/drivers/macintosh/ windfarm_smu_sensors.c: machine_is_compatible ("PowerMac9,1")) &&
However, this is the same updates-testing kernel that didn't work for me, even though it has the patched therm_pm72.c driver I needed for my PowerMac7,2 and PowerMac7,3 machines. But it seems like trying FC4 and then doing a "yum --enablerepo=updates-testing update kernel*" might get you somewhere close.
Benjamin Herrenschmidt benh@kernel.crashing.org is the author for most of the thermal support for the PowerMacs. I never see him on the fedora lists. He can be found on linuxppc64-dev and also on debian-powerpc
On my web page (http://carlstrom.com/winunix.html) I have links to the various linux/ppc mailing lists such as linuxppc64-dev, fedora-ppc, debian-powerpc, and yellowdog-devel if you want to look around the archives for PowerMac9,1 stories.
As far as YDL goes, there is a 4.1 release now available for $$$ and perhaps the ISO's will be out soon. there was a 4.0.91 beta that people seemed happy with as far as PowerMac support went. For me, the package selection of FC4 is so much better than YDL that I don't want to go back.
Good luck,

Hardware Overview:
Machine Name: Power Mac G5 Machine Model: PowerMac9,1 CPU Type: PowerPC G5 (3.0) Number Of CPUs: 1 CPU Speed: 1.8 GHz L2 Cache (per CPU): 512 KB Memory: 1 GB Bus Speed: 600 MHz Boot ROM Version: 5.2.2f2
I have tried YDL 4.0.1, but at least during the prep stage, after boot and before the actual install took place, I experienced the problem. This, plus the fact that I couldn't figure out which of my 2 internal SATA drives YDL would be installed on. made me bail.
Wow, this is the first really informative response that I have gotten as per this issue on any PPC Linux list!!!! Please tell me, if I try to install Fedora Core 4 and do manual partitioning for "sdb" SATA internal drive #2 on my G5 can I decide which drive to install Fedora on? I just want to make sure that I don't have to bail because I think Fedora is going to erase and install on my OS X install drive "sda".
I am in the process of downloading the Fedora Core 4 PPC CD's, so I was wondering if anyone on the list has experienced these problems.
Cheers,
Brian

Actually, my post didn't go to the list because its still awaiting moderator approval because of a "suspicious header" although the automated response didn't tell me which header was the problem. I've sent other posts to fedora-ppc in the past and I don't think any of them have gotten through becuase of this problem.

Unfortunately I can't help you there. All of our machines are linux/ppc only, no Mac OS X. The only thing I can suggest is disconnecting the Mac OS X drive to be safe during the install. If linux/ppc isn't booting after installing on sdb, you might try switching the drive so linux/ppc is sba and Mac OS X is sdb, since I think Mac OS X can handle booting as the second drive if I recall correctly.

Is this just an issue of changing the drives physically or are there some sort of master slave switch that I have to change as well?

I believe that with SATA, the concept of master and slave is gone. If the cables will reach, you could just switch the cables, otherwise switching the drives would work. You probably should switch the drives and try to boot Mac OS X on the "b" drive to see if that works before bothering with the linux install.

YDL 4.1 is based on FC4, and has a 2.6.15 kernel. It's is currently held up in late beta as they try to get support for the dual/quad core G5s. I think ydl.net members can get the ISOs now, and they do release the ISOs free about 2 weeks after the release is finalized.
Package selection is an issue, down the road, but they do have a little more polish and support for Macs... If they'd just keep current with updates and extras....

Yes, you have control over which drive(s) are used, even for auto-parition (which offers a checkbox for 'review partition scheme' that lets you double-check what it is going to do).
