Konstantin Belousov 37f780d3e0 Disable x2APIC for SandyBridge laptops with Samsung BIOS
From the PR:
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.
