Here's my comment from #22336, since it's closely related...
I've got a similar problem on my laptop (Dell Inspiron 9300, 1.73GHz Centrino, Kubuntu 7.04 [upgraded from 6.10]). The problem wasn't there before the upgrade. I set the CPU Policy to "Dynamic" (aka "on demand"). When doing normal browsing for example: $ cat /proc/acpi/thermal_zone/THM/temperature temperature: 51 C At this point, the CPU is at 800MHz. Then, let's do some intensive task, like compile a simple app. The CPU goes to 1.73GHz as expected. but just after 2 seconds: $ cat /proc/acpi/thermal_zone/THM/temperature temperature: 66 C And it continues to increase! There is NO WAY that the temperature is rising by 15C in 2 seconds! Also, just being idle and setting the CPU Policy to "Performance" raises the temperature to 62C (and raising)... And of course, when doing too intensive tasks, the trip point will be reached and the system will shut down. As I said, this didn't happened when I was on Edgy... -- kernel 2.6.20-xx incorrectly claims processor overheating https://bugs.launchpad.net/bugs/94862 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
