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.
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.
