No. This message is interesting because as a consequence of an overly long hrtimer interrupt the hrtimer interrupt will be deferred so tasks can make progress. That means for the time of deferral there will be no hrtimers fire, which is confusing if the message is removed because you cannot figure out the reason. Thanks, tglx
