Description Roberto D'Auria 2011-07-11 18:10:06 UTC

Description of problem:

When I use the version 6.14.1 (the latest one) of ATI Radeon open source driver, my video card hits 80-85° C while doing nothing special (only gnome shell session open). In some cases it stopped my battery from charging for the extreme overheating.

My video card is a Radeon HD 4200, as reported by lspci:

01:05.0 VGA compatible controller: ATI Technologies Inc M880G [Mobility Radeon HD 4200]

I'm sure it's the ATI driver because if I switch to Catalyst (closed source) drivers it works well and the temp is between 45° and 55°. 
Unfortunately, using the Catalyst drivers causes this bug: https://bugzilla.redhat.com/show_bug.cgi?id=710258 so I'm stuck with GNOME3 fallback mode.

How reproducible:
- Use F15 with xorg-x11-drv-ati and a Radeon HD 4200


Steps to Reproduce:
1. Use F15 with xorg-x11-drv-ati and a Radeon HD 4200
2. Check the temp of video card using lm_sensors
  
Actual results:
Overheating

Expected results:
A normal temperature

Additional info:

Feel free to ask me additional info if required.
