No problems with thermal control? I am still experiencing thermal

have the problem anymore, so I don't really get why Debian based
distros are still experiencing this.
I just tried Xubuntu Dapper PPC desktop version and the problem is
still there.
Please tell me more about what the problem actually is and try with
2.6.17. Thermal control should be implemented by the windfarm_pm91
module on these machines (make sure you also have cpufreq loaded and
windfarm_cpufreq_clamp).

Hi again Ben,
OK, I have gotten the yaboot issue sorted from my side. Firstly, with
the "experience" that I have had trying to get Linux working on my G5
single, I can say that I have developed a rule of thumb: if when
booting from either a live CD to install or booting from an install
CD and my fans start revving like a jet engine, 9 times out of 10 the
issue with the thermal control will not have been sorted in the
actual install.
I have tried installing Debian Sarge PPC 3.1r2, but it can't find my
CD/DVD drive (came with the G5). Debian Etch beta 2 (latest I could
find) does install, but at system boot, it runs some scripts, which
seem to go without a hitch, then it complains about a 'module unknown
not found', then it tries to mount /dev/sdb3 on /root (which fails
with a 'no such device'), then comes a "no such file or directory'
and then the system defaults into BusyBox and I get the error "/bin/
sh: can't access tty: job conrol turned off". This same scenario
occurs with the Xubuntu PPC Dapper Drake LTS install version. An
install with the "desktop" or "live" CD version of Xubuntu Dapper
reaches the GTK login screen and then freezes. This may be related to
similar behavior that I have seen with sound card issues on the G5 in
earlier versions of Ubuntu and Fedora Core 4, but it could also be
related to the above mentioned problem with install version of
Xubuntu, despite the fact that I don't see the same messages (there
are some error messages, but they don't seem to be fatal).
All of the install disks that I can boot show the symptom of a
problem with thermal control. Whether the actual installs function
the same way, I can't say as I haven't been able to get any up and
running on my G5. My gut feeling however, is that the problem still
exists.
BTW, the Etch gets a repeat error of "Error while running 'modprobe -
v sbp2'" a couple of times at the very beginnning of the install, but
the install continues and doesn't seem to be fatal. The Etch
yaboot.conf also can't boot into OS X, which is by now an old issue
that Ubuntu seems to have solved.
Cheers,
Brian
