I believe so. Although it didn't appear in my 32bit testing w/ kvm, but I suspect that is due to my distro userland setting lots of timers so that we don't hit those multi-second idle times, which could overflow 32bit nanoseconds, or maybe some other kvm quirk. Anyway, let me know if your testing goes well. Thanks so much again for noticing and bisecting this down. -john -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
