Subject: MCP limit log messages, 2.6.36-rc4

I've been getting regular MCP limit log messages on a Dell Studio 1458 
(i5 CPU) with an A02 BIOS. With the attached debug hack it prints the 
following values:

[   33.605098] intel ips 0000:00:1f.6: MCP limit exceeded: Avg power 
30123, limit 1023
[   38.597998] intel ips 0000:00:1f.6: MCP limit exceeded: Avg power 
21697, limit 1023
[   43.590917] intel ips 0000:00:1f.6: MCP limit exceeded: Avg power 
15390, limit 1023
[   48.583821] intel ips 0000:00:1f.6: MCP limit exceeded: Avg power 
43370, limit 1023
[   53.576740] intel ips 0000:00:1f.6: MCP limit exceeded: Avg power 
64728, limit 1023

This is an idle machine which starts printing these messages about 30 
seconds after boot. Any thoughts?
