<para>Avoid a kernel panic booting on a system with x2APIC enabled
by the BIOS. This option does no harm if x2APIC is not enabled
or not available, but it's recommended to enable x2APIC in the
BIOS setting for a modern 64-bit x86 system.</para>
<para>Support running the interrupt controller of 64-bit x86

has no effect, but also does no harm if x2APIC is disabled by the
