The effect seems to be that it causes some kind of OOM condition
during boot under Xen:
Dec 14 08:00:04.637998 [ 22.584134] Out of memory: Kill process 2747
(exim4) score 2 or sacrifice child
It's not quite clear to me but I think the problem may be hardware
specific.

See in particular this, which is the host serial console output:

Thanks,
