When the system is booted from a number of cpus less or higher than 2, the system crash

• With an only CPU, the system crash during the booting start. It seems related with the cpu enumeration, in acpi_setup()

• With 3 or more CPUs, the system crash after boot the first AP. It only happen when paging is enabled. Disabling the paging configuration, all CPUs got to boot successfully. But paging is needed to get that the CPUs are useful.
