It should concern us all that an any code we stuff in a domain can
bring fron the whole box, so this is certainly relevant to the list.

Are you posting an event from libOS?
May I suggest, for bringup, to put:
int do_map_myself = 0;
!!! In your testos (not crt_init.c)
This will make your OS run 100% real mode, and will not use any MMU
Then in xen:arch/powerpc/hcalls.c printk all hcalls you see that are
not Dom0 and not console.
braket your printk with
to make sure your that output is not buffered
