I've pushed Ubuntu to a friend, but after upgrading her laptop to Karmic she has been experiencing this too.
The fan is working at full speed and the CPU is getting very hot. The result is that, after a while, when the CPU temperature reaches somewhere above 90 degrees celcius, the system "freezes" (I can't help thinking that's a bad word for something actually related to overheating). Then, after a forced shutdown (holding down the power button), it needs to cool down for a while before we're able to turn it on again. As a temporary workaround I've told her to blow into the heatsink hole for a while, to lower the temperature when it's getting close to the critical point. Removing the battery doesn't seem to make any difference. It's an Acer Aspire-something. I don't remember the specs, but if I can be of any help, please tell me what you need to know. -- regression in karmic thermal control https://bugs.launchpad.net/bugs/432670 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
