[Mactel-linux-users] macbook pro v2.1 ati weirdness

[k11stan <k1...@gm...>]

hey every1 - occasionally if I do not boot to osx for an extended period of
time (roughly a month), the fan behavior (and likely also throttling) seems
to get very weird ( the fans randomly rev up , the temps seem to spike , and
the whole setup gets really unstable) .. after i boot to osx the problem
seems to go away .. is there any way to preserve the nvram values that osx
likes to set ? I'm using 2.6.25 with mactel patches and version 8.51.3 of
fglrx .. I throttle the card using radeontool ...thanx for any suggestions

I guess this is no real help, but for reference I can say that the
fans on my ATI-based MBP (2,2) were also acting up now and then. I
didn't boot into OSX a lot, so where that is related I have no idea.
However, I can say that my current MacBookPro4,1 (nVidia based) is a
LOT more sane when it comes to fans - and even when they spin up (due
to occasional high load) they don't make nearly as much noise. On the
downside, I never had any "applesmc: wait status failed" messages on
the old system, whereas it seems that polling this info (fans, temps
etc) fail - and then retry successfully - quite often now. I don't
know whether this is actual HW differences or if the driver just works
differently in newer kernels. BTW: I have not booted OSX on this box
for at least 3 months.

             Hope this was of some use for someone / Jonas

 From here I don't experience any anomaly's
accept when configured wrong.

(on a clean system(debootstrap));
I usually just apt-get powersaved
then adduser "yourename" powerdev;
then all is good.
(issues: when running anything with flashplayer
do a powersave -e Powersave; powersave -l);

then you should have the fans under-control.

that is(sorry accidentally got drunk(presidential inauguration);
having acpi; acpid installed first.(before powersaved, or you'll run 
into issues);

Yes, it sounds familiar that I had to turn of a lot of the frills to
make fans sane.

I have not personally had the opportunity to try it, but I recall that
one of the issues was that you needed some fiddling due to the fact
that the (single) button is more or less UNDER the trackpad. I believe
the stuff you need is here:
