I think you forgot to reserve CPU 0 for BSP in cpuid mask.
Sorry for the late reply.

I'm not familiar with BSP.  Do you mean in get_cpuid(),
I should reserve 0 for physical cpu0 in BSP ?

Would you please share more detail ?
BSP stands for "Bootstrapping Processor". In other word,
BSP is CPU0.
.


Ha, how foolish I am.

And yes, cpu0 is not reserved when apicid == boot_cpu_physical_apicid
comes true.

Will update the patch.

Thanks. :)
