I tested the config on a couple of different systems. Unfortunately I
wasn't able to reproduce the problem. It booted always fine even on multiple
tries.

I had to adapt the configuration slightly to boot in my setup.

The configuration also was not complete, i had
to press return a few times (are you sure you sent me the correct file?)

One merging issue I noted is that you put the perfctrs and mce self
on the same vector. The attached patch fixes that.
