Dear Kernel Gurus:
Below is a problem that I am unable to explain along with relevant(?) info. Please let me know if I should provide additional debugging information. Thanks in advance for your assistance!

[1] Problem: HP Pavilion zv5000 laptop idle temp is 17 degrees higher when running most recent kernels (57C versus 40C).
[2] Brief Description
Newer kernels (noticed starting with 2.6.27.3 but could have started anytime past 2.6.26.7) result in a much higher idle CPU temp. Physical temperature reading of exhaust from primary cooling fan and the regular triggering of secondary cooling fan confirms this (it is not a readout scaling issue). The kernels and temps below:
2.6.26.7 Idle temp 40C
2.6.27.3 Idle temp 57C
2.6.28 Idle temp 57C
The only third party kernel module installed that is not part of the official kernel source is: madwifi-ng. However, the problem occurs even when this module is not loaded.
The .config file used for the newer kernels was imported from the working 2.6.26.7 .config file.
[3] Environment (when running the hot 2.6.28 kernel)

Physical temperature reading of exhaust from primary cooling fan and the regular triggering of secondary cooling fan confirms this (it is not a readout scaling issue). The kernels and temps below:

CPU frequency scaling not working perhaps? What's your dmesg output from
bootup look like? Is the acpi-cpufreq driver being loaded?

I thought I had checked this but...the problem goes away with "nolapic" (i
had configured lapic into previous kernels, even though a uniprocessor,
because it solved minor IRQ issues). Broken HP APIC? I fixed the IRQ issue
by forcing IRQ balancing. Interesting that this starts with 2.6.27.x.
Many thanks for your response.
