o Kdump second kernel boot fails after a system crash if second kernel is UP and acpi=off and if crash occurred on a non-boot cpu. o Issue here is that MP tables report boot cpu lapic id as 0 but second kernel is booting on a different processor and MP table data is stale in this context. Hence apic_id_registered() check fails in setup_local_APIC() when called from APIC_init_uniprocessor(). o Problem is not seen if ACPI is enabled as in that case boot_cpu_physical_apicid is read from the LAPIC. o Problem is not seen with SMP kernels as well because in this case also boot_cpu_physical_apicid is read from LAPIC. (smp_boot_cpus()). o The problem is fixed by reading boot_cpu_physical_apicid from LAPIC if it is a UP kernel and CRASH_DUMP is enabled.
