What does "hrtimer: interrupt" mean?

Posted on November 24, 2014

I noticed a message on my console today that simply says: “hrtimer: interrupt took 3777162 ns”

Does anyone know what this means? A simple Google search makes me think that this is a harmless message, but I just wanted to double-check. I haven’t done any experiments with my server, so I’m just wondering what triggered it. Thanks for any help.
