I agree, I have seen this on a Lenovo T60 myself. And it also occurs on my
Latitude D830. For the most part, I can fix it by removing acpi_cpufreq and
reloading it, but at times the module is in use and thus cannot be removed.
I think this is a kernel bug of some sort, as it occurs in vanilla kernel.org
kernels as well.
