With lifting cpu0 apic id to 0x10, on Nvidia chip set, it could pass the
calibrate_delay in bsp. But it can not start core1/node0.

It looks like the timer interrupt goes to the second CPU.

This is a known race (fallout of the hotplug CPU code, fix is on my todo
list), but fixing it would probably not help you when the timer goes to the
wrong CPU.
Actually when it went through calibrate_delay it is likely
broadcast to all CPUs, which is definitely wrong.
