And as luck would have it, I can't reproduce the problem any more. I've shutdown -p now'd literally 6 times in a row without any sort of lock up, and this is running on the old kernel. The same behaviour is now seen with the new kernel. So, the 2-3 times I've seen "shutdown -p now" not fully power off the machine were either flukes, or who knows what/why. I simply can't reproduce the problem any longer.
