That seems to be the case.  Since we have no always-on intelligence, we
are at the mercy of default PMU actions on its own to bring up the CPU.
~ If we can't "fix this in the almighty userspace" without a CPU either,
then it's a problem.  As it stands, the problem is hidden by a living
battery "filling in".

This is yet another case for an always-on MPU to solve it in future designs.
