Ubuntu 16.0.4 LTS boot crash on xen 4.6.5

domain

I'm trying to find out a crash when booting a Ubuntu 4.8.0-32-generic
dom0 on a recent xen 4.6.5.

Some information about hardware and software versions:
Supermicro X10QBi, Version 3.0, Build Date 05/04/2016 12:38:52
CPUs 4x Intel (R) Xeon (R) CPU E7 -8890 v4 @ 2.20GHz
RAM 6291456 MB (DDR4 1600MHz)

Xen version: 4.6.5 (ubuntu package)
Xen options: placeholder loglvl=all guest_loglvl=all console=com2
com2=115200,8n1 dom0_mem=1048576M,min:1048576M,max:1048576M

Any idea what is causing the BIG boom?

Can you please try to translate RIP to source file + line number using
addr2line?

And the obvious kernel addresses on the stack, too, please?

The kernel config might help for further diagnosis.
