While writing the previous comments, the machine crashed again, this one
slightly different:

(XEN) domain_crash_sync called from entry.S (ff188600)
(XEN) Domain 0 (vcpu#1) crashed on cpu#1:

(XEN) Domain 0 crashed: 'noreboot' set - not rebooting.

I set noreboot, because I wanted to catch these. Here is the addr2linux output
of the various pieces:
