Hi!

When I try to boot NetBSD/Xen-amd64 Dom0, then I get this crash:

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

(XEN) Domain 0 crashed: rebooting machine in 5 seconds.

The kernel image is there:

(XEN)  Xen  kernel: 64-bit, lsb, compat32
(XEN)  Dom0 kernel: 64-bit, lsb, paddr 0xffffffff80100000 -> 
0xffffffff80b571d8
(XEN)  Dom0 symbol map 0xffffffff80b571d8 -> 0xffffffff80c44a68

The RIP is outside of the kernel's .text section, so something is going very 
wrong here.


This is the boot message:
