Is this just an artifact of RT > kernel's better perspective/granularity? thanks for reporting this, this is indeed a bug in -rt2. What happens is that the RCU priority booster kernel thread is in uninterruptible sleep: $ ps aux | grep -i prio root 31 0.0 0.0 0 0 ? D Feb05 0:00 [RCU Prio Booste] that artificially increases the system load average by +1.0. I've fixed this in my tree and it will be in -rt3 today - it's harmless otherwise.
