Hello Yin,

thanks for your interest in McKernel!
Please see my answers inline.

I believe that for the kernel code you can go with x86_64 as well, but to
be honest
we haven't used the KNC configuration for quite a while now.
We've been mainly focusing on the upcoming KNL version of the Xeon Phi,
which will be primarily standalone and for which the standard Xeon
configuration
is currently the most similar.

The version you are using is mainly for partitioning a Xeon chip.
I am currently away and I am not sure how soon I can investigate this, but
we could
try doing it together.

Have you tried to disable the SSE initialization code and compile/boot that
way?

Best regards,
