So, if I reboot the system then all the CPUs are online again. Furthermore if I rerun cpu_frequency_governors then CPU1 has not gone offline (all of this with the 3.2.0-12.21 kernel) after it finishes. This makes it difficult to determine if the problem is really gone in the mainline kernel. I would potentially need an ISO spun with the mainline kernel in it.
