Description Maxim Britov 2017-06-07 05:26:14 UTC 
1. With kernel 4.11 upowerd[pid]: failed to get data: Can't open «/proc/timer_stats»: file not found
2. 100%cpu after gnome-power-statistics

upstream bug https://bugs.freedesktop.org/show_bug.cgi?id=100626
commit: https://cgit.freedesktop.org/upower/commit/?id=798588a480eaae50368bed75fc78f8314523b2a3

On my gentoo it silently applied and compiles fine.

Reproducible: Always
