With 2.6.29.4-rt16 I get after some time under load following warnings: NOHZ: local_softirq_pending 02 NOHZ: local_softirq_pending 02 NOHZ: local_softirq_pending 02 NOHZ: local_softirq_pending 02 NOHZ: local_softirq_pending 02 NOHZ: local_softirq_pending 02 NOHZ: local_softirq_pending 02 NOHZ: local_softirq_pending 02 NOHZ: local_softirq_pending 02 NOHZ: local_softirq_pending 02 Clocksource tsc unstable (delta = 65308166 ns) Seems that TIMER_SOFTIRQ is not run when properly. Any idea who caused this?
