Description of problem:
Laptops with ATI/AMD Radeon graphics (for example HP EliteBook 8530p with ATI HD 3650) runs very hot and causes laptop overheating and thermal shutdowns making Fedora 16 unusable.
Version-Release number of selected component (if applicable):
Fedora 16 Alpha x64 live-CD / Linux 3.0.0.
Steps to Reproduce:
1. Boot Fedora 16 Alpha live CD.
2. The laptop becomes very hot and overheats, even when there is no CPU
usage and the system is idle.
Laptop runs too hot, and overheats often causing thermal shutdowns and crashes.
Laptop runs cool like in Windows, or when using the proprietary fglrx driver.
As a default power_profile "default" is in use:
$ cat /sys/class/drm/card0/device/power_profile
Changing the power_profile to "mid" or "low" makes the temperature go down at
least 10-20 degrees celsius on my laptop:
$ echo low > /sys/class/drm/card0/device/power_profile
This overheating issue is caused by a driver bug or unimplemented features in the opensource radeon driver. For the time being the "default" radeon power_profile should not be used as a default.
"dynpm" might be better default power_profile..
Hmm, actually "dynpm" doesn't seem to be accepted option for some reason. "auto" seems to be valid, I'll try if that works.
I don't think it makes much more sense if we concentrate all our efforts on the upstream bug. Closing as duplicate of bug 682851, which is closed against the upstream http://bugs.freedesktop.org/show_bug.cgi?id=36438

I'm running FC16 with a Lenovo - ThinkPad Edge quadcore....
It was impossible to work, computer shutting down almost all the time, it was running with 90 degrees :S, after your suggestion:
echo low > /sys/class/drm/card0/device/power_profile it is now down to 65degrees!!
Is there anything else that could be done in order to run with lower temperatures than this ?
The upstream bug is this:
I recommend you to comment on that upstream bug, and also post to dri-devel mailinglist about the issue. It seems AMD/ATI developers are not putting efforts into fixing/implementing proper power management for the opensource radeon driver.
.. and thus the radeon driver is unusable out-of-the-box in laptops, especially when testing new Live CD's.. quite often the laptop overheats and shuts down before you even get to the desktop to be able to switch the power_profile!
It's very annoying and frustrating.
And another upstream bug about the same issue:
