Fenghua Yu 522e664644 x86/apic: Disable I/O APIC before shutdown of the local APIC 
In reboot and crash path, when we shut down the local APIC, the I/O APIC is
still active. This may cause issues because external interrupts
can still come in and disturb the local APIC during shutdown process.

To quiet external interrupts, disable I/O APIC before shutdown local APIC.

[ I suppose the 'issue' is a hang during shutdown. It's a fine change nevertheless. ]
