With powertop 2.5, see these 3 report taken a minute apart with no
change of load.
All I did was remove the yubikey and put it back in, and unload wlan0

The battery reports a discharge rate of 19.9 W
The estimated remaining time is 3 hours, 23 minutes

No real change either (little drop from removing wireless, but not 10W)
The battery reports a discharge rate of 17.8 W
The estimated remaining time is 3 hours, 43 minutes

and power went up 0.4W (normal variance unrelated to yubikey).
The battery reports a discharge rate of 18.2 W
The estimated remaining time is 3 hours, 38 minutes
Summary: 1284.1 wakeups/second, 36.2 GPU ops/seconds, 0.0 VFS ops/sec and

301 mW 6.3 ms/s 207.0 Timer hrtimer_wakeup
168 mW 2.8 ms/s 115.6 Interrupt PS/2 Touchpad / Keyboard / Mouse
Is anyone closer to fixing this bug? It's impossible to get real battery
usage and due tuning with it present.
Thanks
Marc
