I have a similar laptop, a T400, and I have been seeing the same problem lately.

This is not a laptop-mode-tools bug. It is believed to be a kernel bug in the cpufreq driver. 

To confirm, could you try to reproduce the problem after disabling the cpufreq module? If possible, also ensure that no other system tool plays with the cpufreq driver.

This one is not reproducible in the latest 3.3 kernels as reported by the users and has been marked as fixed-upstream [1]. I myself am on 3.3 kernel and have not seen this issue. I could have reassigned this bug to the kernel team so that they backported the fix, but the bugzilla has no patch attached. Finding the right commit that fixed the bug will require bisecting the 3.3 release.

Still am adding the kernel team. Just in case they have any further information.
