Dan, please *don't* file another bug. I'm not sure what Paul is trying to say, but the D600 is one of the machines that has this problem, and is the machine I used to examine the bug. It has also rather been seen that the patch doesn't fix it, but unfortunately it is very difficult to work on because it appears to be an obscure race condition that appears and disappears, and I haven't had it in quite a long time.

If you are comfortable with doing so, try my method listed earlier: comment out the verification steps in __cpufreq_set_policy in cpufreq.c. You need to keep the ACPI PPC from being used to limit the maximum frequency. This applied to 2.6.15, so you might need to make some changes to the process for it to work on newer kernels.
