powertop states broken CPU usage on nvidia wake up from D3

Summary: 2320.0 wakeups/second,  0.0 GPU ops/seconds, 0.0 VFS ops/sec and 1427.4% CPU use

Usage       Events/s    Category       Description
            11939 ms/s      13.6        kWork          commit_work

EDIT: it states such huge CPU usage even when the dGPU is in D3cold state, and it happens only on AC as well.
