Hi, I am suspecting that in kernel/ipipe/timer.c:select_root_only_timer()
When t->irq == per_cpu(ipipe_percpu.hrtimer_irq, icpu), a condition to test the timer rating against current timer rating before installing the timer is missing. That is t->rating > percpu_timer->rating (combined with same irq #) before the condition becomes true. Here's screenshot: [cid:image001.png@01D3E177.63116AC0] Phong.
