CentOS virt - Mar 2017 - Xen C6 kernel 4.9.13 and testing 4.9.15 only reboots.

Updating my CentOS 6.8 Xen server with new 4.9.13 kernel yields a kernel
boot message of a few like "APIC ID MISMATCH" and the system reboots
immediately without any other bits of info. This is on a Dell R710 with
64GB RAM and 2x 6-core Intel CPU's.
As an additional test, I installed and attempted to run the current
"testing" kernel of 4.9.16 with the exact same results.

Anyone have an idea? The 3.18.x series runs without issue of course.

Thanks

PJ

Try this kernel (the noarch kernel-doc is not done yet), but that is not
a required package:

https://people.centos.org/hughesjr/4.9.16/x86_64/

Let me know if that works or not .. we can try adjusting some other
config settings.

Don't worry about the centos.plus dist tag .. that will change when we
subnit it via the regular process.

Thanks,
Johnny Hughes

I think the APIC ID MISMATCH is an expected and ignorable error .. see:

https://patchwork.kernel.org/patch/9539933/

I applied that patch and I am building a 4.9.16-23 right now, I 'll
publish it when it finishes.  Maybe with the error gone we can get a
better error in the console.
