Well, disabling IO APIC is no longer recommended for SMP since 2.10. As about LAPIC initialization failure, could you set boot_verbose and take a photo or setting up a serial console to give me the dmesg before the panic? And I need the output of 'acpidump -t' and 'mptable' (you could run these two commands from a UP kernel). Best Regards, sephe -- Tomorrow Will Never Die
