Hi Sebastian Please refer to my another patch comment. Basicly, AP is running HLT in 0x10038, but it can exit due to some reason, here QEmu want to raise it up . But after AP exit from HLT, it can't return to it because the code was overrided by grub and no HLT loop there. Then AP had gone away... -- regards Yang, Sheng -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
