Bug Description

I've noticed spamming from the kernel in /var/log/syslog regarding exceeding the CPU and MCP thermal or power limits:

Sep 1 11:36:28 demeter kernel: [98490.237702] intel ips 0000:00:1f.6: MCP power or thermal limit exceeded

Sep 1 11:37:13 demeter kernel: [98535.210010] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded
Sep 1 11:37:18 demeter kernel: [98540.212247] intel ips 0000:00:1f.6: CPU power or thermal limit exceeded

I get one message every few seconds. There seems to be no other effect, as my system appears to be running at a reasonable temperature (isn't hot to the touch), and doesn't crash or hang. Perhaps the only thing is that battery seems to run out fairly fast, though I can't provably say there is any relation between the two issues :)

In any case, sensors report the following:

Hi Mathieu,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Does not make sense a automated message suggest usage of a mainline kernel since Maverick kernel is just the lattest stable. I have this issue in my i3 Vaio VPCEA21FX notebook. More details below:

Just for information, since the best bug report dont links to Maverick: In a post in linux-kernel list [1], a guy suggest a inspection in /sys

Mine output is:
