Description Christian Muehlhaeuser 2018-03-19 00:48:25 UTC

While playing a YouTube video in Firefox, powerdevil keeps excessively logging the following output. Note that I've cut it down to just a fraction of a second of log messages, but this keeps going on as long as the video is playing.

The power inhibition seems to work fine, but the logging alone seems to slow down the system.

This looks like a Firefox bug to me, it shouldn't constantly request an inhibition but only when the video starts and then when it stops/pauses. Please report this issue to them.

Will do, out of curiosity: what does "can't contact ck" mean?
