Include Samsung laptops/computers in the x2APIC Sandy Bridge blacklist.
Almost always, my Samsung RF511 laptop could not boot with
x2APIC enabled in the kernel. It froze during SMP initialization,
shortly after "ACPI APIC Table: <SECCSD LH43STAR>" was printed
to the console. When the kernel is instructed not to use x2APIC,
the system boots correctly.
