Is powertop freezing? did you see the change of Top causes for wakeups? 100% C0 residency indicated the system has 100% cpu utilization. when you used poll-mode, did you set cpu-threshold to 1s in /etc/power.conf? It would be interesting to see how the compilation caused 100% cpu utilization. I tried to do the nightly, everything works fine. Can you give more details how to replicate this issue? By the way, we didn't change cpupm related code for a long time, does this issue exist on the other build?
