I have seen that a lot of people are having this same issue. I am running a Lenovo V570 i5 4 core, 6 gigs of ram, and am running 11.10 Onieric Ocelot.
On my system monitor graph it shows CPU at 20%, when I open the monitor it shows core #1 at around 90%, the other cores fluctuate at or below 5-12% if even. Now this seems like a really terrible balance of power between the cores, especially with so much stress on one core only, when these things are designed to work with 4 cores and not at such high temps. My current readings say 64 degrees Celsius, this does not seem normal for any cpu, and I am seriously considering, working on my windows7 partition until I see a real solution to this issue or upgrading to 12.04 right away when it comes out... I have seen countless things saying it has something to do with the Kernel, the kernel on mine is the same as when I upgraded, I really do not like messing with it, as when I had 11.04, I did tinker with it due to the freeze issues I was having, and that just made worse issues. I like this version 11.10 and would like to keep it for a while, but without the fear that my core is going to fry! So any help would be much appreciated! I did try changing a couple things in ACPI, and restarting this did not help, and here I am. I tried one thing prior to that that was listed under a different computer brand, but it would not do a make on the file.
I really need help with this, I rely on this computer for a lot of things, and love this OS! Please help so I do not need to resort to my Microsoft partition! PLEASE!

00015 cpufreq ---------------------------------------------------------
00016 cpufreq Test 1 of 1: CPU P-State Checks.
00017 cpufreq For each processor in the system, this test steps through
00018 cpufreq the various frequency states (P-states) that the BIOS
00019 cpufreq advertises for the processor. For each processor/frequency
00020 cpufreq combination, a quick performance value is measured. The
00021 cpufreq test then validates that:
00022 cpufreq 1) Each processor has the same number of frequency states
00023 cpufreq 2) Higher advertised frequencies have a higher performance
00024 cpufreq 3) No duplicate frequency values are reported by the BIOS
00025 cpufreq 4) Is BIOS wrongly doing Sw_All P-state coordination across cores
00026 cpufreq 5) Is BIOS wrongly doing Sw_Any P-state coordination across cores
