Bug#404090: GPU temperature skyrockets after starting X

[Alberto Gonzalez Iniesta]

Package: xserver-xorg-video-ati
Version: 1:6.6.3-2
Severity: important

Hi X Strike Force,

I'm fighting with my new (2nd hand) iBook G4 and found the following
behaviour in it:
(I don't run ?dm, the computer starts in text console mode)
- Start X, the GPU temperature starts to rise *very* quickly
- The temperature will reach 80 Celsius and fan will turn on
  (don't know how far it would go)
- No matter whether you remain in X or quit, the temperature won't
  descent

Now, if you suspend the laptop (by closing the lid) and resume
(just after a couple of secs.) not only the temperature will be
much lower, it will remain that low (~60C). That will happen
whether you suspend after quitting X OR even if you stay in X before
and after resuming.

So the problem seems to be in the initialization of the video card.

My video card conf:
Section "Device"
  Identifier      "Generic Video Card"
#  Driver          "radeon"
  Driver          "ati"
  BusID           "PCI:0:16:0"
  Option          "UseFBDev"
  "true"
  VendorName      "ATI"
# Option          "AGPMode" "4"
EndSection

I've tried both 'radeon' and 'ati' drivers and AGPMode 4 and none (1).
All with the same result. So it could be a kernel (module) problem
(2.6.19.1).

Thanks,

Alberto
