It really looks like amd76x_pm is causing the time loss. Sadly, I have
no idea how to avoid this. What happens when the pm-timer wraps around
while the processors are in C3 sleep state? How is this wrap detected
at all? Is there anything I could put into amd76x_pm? It's no problem
detecting a timer wrap there.
