Bug Description

My laptop shut itself down today and I found this in the logs:

Aug 16 01:03:17 tas kernel: [22022.641233] ACPI: Critical trip point
Aug 16 01:03:17 tas kernel: [22022.641233] Critical temperature reached (100 C), shutting down.
Aug 16 01:03:17 tas kernel: [22022.655806] Critical temperature reached (95 C), shutting down.

The fan was not running at a noticable level when this happend. It hasn't happend yet with the hardy kernel, it started to happen when I upgraded to inrepid. This is a Lenovo T60, I attach the lspci output

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

My X61 Thinkpad (Ubuntu 8.10) shuts down after 30 to 60 minutes of watching a Flash-intensive web site (e.g. episodes on thedailyshow.com). In /var/log/messages I see:

Apr 5 11:34:23 x61 kernel: [101330.895345] ACPI: Critical trip point

$ uname -a
Linux x61 2.6.27-11-generic #1 SMP Thu Jan 29 19:24:39 UTC 2009 i686 GNU/Linux

I found that the fan never goes above 3000rpm. Doing

rmmod thinkpad_acpi && modprobe thinkpad_acpi fan_control=1
echo "level 7" > /proc/acpi/ibm/fan

got the fan up to 3900rpm and kept the CPU temperature around 65 to 70C. So there's a problem with the CPU fan control in a stock Ubuntu 8.10 install.
