Bug Description

Binary package hint: xserver-xorg-video-ati

When I'm doing a demanding CPU activity (ripping a CD, doing OCR, etc), the computer shuts itself down due to overheating (more than 99 C).

I've tried running sudo sensors-detect but no modules were loaded.

I've also tried booting with option "acpi.power_nocheck", but to no use.

I've also tried adding options radeon modeset=1 to /etc/modprobe.d/radeon-kms.conf.

Lastly, I updated my BIOS from the vendor's webpage, but it didn't help either.

This is more likely to happen while on the open-source ATI drivers.

Given that it doesn't happen with the proprietary fglrx drivers, it's definitely related to bug #373669. See comments 16 and 17 in that bug.

Yes, thanks for pointing that out. I saw that comment yesterday. I tried installing the latest 2.6.35 kernel from the ppa (The maverick backported kernel), but the problem persists. Although I get an extra sensor for the video adapter, the fans are not turned on automatically and I still get very high tempreature.

I must correct myself. It DOES happen too with the fglrx proprietary drivers. I tried OCRing and using a clutter-dependant plug in for Banshee and the temperature rose nevertheless and computer had to shut itself down again.
