While I was testing cpu-hotplug (2.6.18-git tree), mistakenly I hot-plugged different-frequency-cpu. Booted with : Itanium2 1.6GHz Hot-added : Itanium2 1.5GHz What happend was ...hrtimer delayed. timers based on jiffies (ex. select()) worked well but timer based on hrtimer can't work. For example, sleep(1) sleeps very long.. Mixed-cpu system works well in other environment ? -Kame - To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
